Short answer: Right-click on the class that contains the master method. Click on "Run As". Click on "Coffee Awarding". The keyboard shortcut is: Shift+Alt+X J (while holding Shift and Alt, printing X; then release Shift and Alt and press J).

Long answer: To be honest, I am not 100% sure why this trouble happens. It might be considering of using a different jdk. I faced the same error. The solution was easier than I imagined. I was used to running my code using Ctrl + F11. But when I ran it equally a java awarding (the manner I described in "short answer"), the problem was resolved. I am not sure if information technology solves other people's bug besides, but it is worthwhile to endeavour. :)

I take been having this problem for a while, but now I have figured it out.

It turns out that Java JDK 12 have both the JRE and the JDK inside the bin folder of the Java 12 JDK. (I accept always believed that JRE and JDK are different application, but it turns out things have changed)

My problem was that I had Coffee JDK 12 installed on my computer

At the same fourth dimension, I had Java 8 (JRE) Installed on my computer.

And then my computer is getting confused.

With my command prompt environment setup to run Java and Javac commands:

I typed the follow commands:

              java -version

// this gave me Java viii

Later that, I typed:

              javac -version

// this gave me Java 12

In other words, my plan is getting compiled with Java 12 and I am trying to run with Java viii.

To solve the problem, I uninstalled Coffee 8 JRE from my computer.

Went dorsum to command prompt to bank check if "coffee -version" and "javac -version" is returning the same version number, and aye, it is returning Java 12.

Tried recompiling my plan again, and running information technology. Information technology Worked!!

It worked! Eureka!!

Running the jar from command line by:

              C:\binder\where\jar\stored>java -jar JarName.jar

I got information which made the problem clearer:

main/Main has been compiled by a more than recent version of the Java Runtime

enter image description here

In this case jar was compiled with version newer than jre supports.

In my instance the event was caused past the JDK version. To solve this I advise to go into your pom file and check the <jdk.version>1.7</jdk.version>.

Later on check java version in your cmd(windows) or terminal ( OSX or LINUX ) past typing : java -version.

Compare the version shown in the concluding\command prompt with what y'all have in your pom file. Make sure they are the aforementioned. Then run your project again.

Y'all tin can check the console first to see the actual fault bulletin then proceed by looking for answers for that error.

My console shows the fault NoClassDefFound for the course jcommander. Your error volition probably be different from mine. The cause of my mistake is that the class jcommander is not in my M2 repository, and then I only accept to add that dependency in my pom.xml. You tin can check if all the form dependencies are all alleged and added in your current config and project build.

I experienced the aforementioned issue, however in my case it was due to the Configuration settings in IntelliJ Thought.

Even though the project SDK (File -> Project Structure) was fix to Coffee eleven, the JRE in the Run/Debug Configurations (Run -> Edit Configurations) was gear up to Java 8. After changing that to Java eleven, it worked like a charm.

~ Answered on 2019-07-03 09:17:02

POSSIBLE SOLUTION If NONE of these solutions worked for yous and so try this... I finally got mine working past deleting the 2 folders ".metadata" & ".recommenders" in the workspace folder. You can discover your workspace folder path by clicking on "File">"Switch Workspace">"Other" in the Eclipse application'south toolbar.

Now I am a complete noob crying my way through an SE degree at San Jose State University. So I am just sharing what worked for me without knowing much knowledge of why exactly. I practise not know what harm or headaches, or fifty-fifty if both aforementioned folders needed to be deleted. But in the finish, it worked for me and it seems the application just recreates fresh versions of those folders anyways.

I promise this helps somebody else. I was suffering with this while working on a projection a few years ago then a job in a newer project started failing a few days ago. I found this post and was trying to recollect what I had modified in my project and then I remembered that I had changed my maven pom and removed the entry for maven-jar-plugin. When you build a jar whose purpose is to be executable, you need to include this then that certain entries go written into the manifest. I opened the quondam project, copied that entry (with some modifications for project name) and it worked.

Now, i don't want to utilise jdk10 and started using jdk8 every bit jvm and tried to run the code which is written on jdk10, so eclipse will through fault of JNI. So, to come out of this error, please add the current JVM path to eclipse.ini file, afterward this copy the written code to clipboard and delete the project in eclipse and create new projection and check in copied code and run.

At that place was no information in my Console so that sent me searching for additional solutions and constitute these - unique to the solutions presented here. I encountered this with Eclipse Oxygen trying to run an old Ant build on a project.

Cause i I had configured Eclipse to apply an external Ant install which was version 1.10.2 which plainly had classes in it that were compiled with JDK 9. In Eclipse I got the JNI error described above (running the Ant build at the command line gave me the reknowned 'unsupported major.modest version' error - the Java I was using on the system was JDK 8).

The solution was to rollback to the embedded Eclipse version of Ant beingness i.x.1. I verified this as the correct solution by downloading Ant 1.10.1 separately and reconfiguring Eclipse to use the new i.ten.1 externally and it still worked.

Cause 2 This tin can likewise happen when yous take the Pismire Runtime settings configured incorrectly in Eclipse's Preferences. Depending on the version of Emmet y'all're running you will need to add together the tools.jar from the advisable JDK to the classpath used for the Pismire Runtime (Dwelling house Entries). More specifically, without a proper configuration, Eclipse will mutter when launching an Ant target that the JRE version is less than a particular required version.

Substantially, 'proper configuration' ways aligning each of the configuration items in Eclipse for running Ant so that they all piece of work together. This involves the Ant Runtime Habitation entry (must betoken to an Ant version that is uniform with your chosen JDK -- you can't run Pismire with JDK 8 when it was compiled against JDK 9); specifying the tools.jar that belongs to the JDK yous want to run Emmet with in the Ant Runtime settings; and lastly setting the JRE environment of your build script to the JDK you want to run Ant with in the External Tools Configuration. All three of these settings demand to agree to avoid the error described to a higher place. You'll besides need to consider the attributes used in your javac tag to ensure the JDK yous're using is capable of executing as you've directed (i.due east. JDK seven can't compile code using source and target version eight).

Moreover If y'all're really just trying to run an Pismire build script to compile code to an older JDK (e.g. less than 8 for Oxygen), this commodity helped gain access to run Emmet against an older JDK. There are Ant plugin replacements for a handful of versions of Eclipse, the instructions are brief and getting the correct plugin version for your particular Eclipse is of import.

Or more than simply you can employ this very good solution to do your legacy compile which doesn't require replacing your Eclipse plugin but instead changing the javac tag in your build script (while using the latest JDK).

~ Answered on 2018-03-27 19:20:32

If the problem occurs while lanching an ANT, check your Ant HOME: it must signal to the same eclipse binder you lot are running.

It happened to me while I reinstalled a new eclipse version and deleted previouis eclipse fodler while keeping the previous emmet dwelling: ant simply did non find whatsoever java library.

This in this case the reason is not a bad JDK version.

My result came from trying to disable the Maven nature from my project and then deleting the pom.xml file. This is bad, very bad, don't do this. If you do, modify information technology back to a Maven projection and hopefully you tin either restore your onetime pom.xml file or create a new one. As soon equally I did that, information technology worked again.

EDIT: I recently ran beyond this trouble once more and this time it was because I had duplicate libraries in my classpath. The ane Maven added (which started with /M2_REPO/.... and so ane I had added (which I should non have done). Even though Eclipse was reporting that it could non find the form, the actual problem was that I had given it two libraries with the same form and it didn't know which 1 to use. Once I removed the second reference, information technology worked.

In my case, Eclipse was giving me this fault but I was getting classnotfoundexception on javax.servlet.http.HttpServletin the logs.

In my case, I was trying to start a spring boot app with exclude module: 'jump-boot-starter-tomcat' in my build.gradle (since I'm deploying on Wildfly).

When nosotros get this fault while running our java application, check if nosotros have some course name or bundle names starting with "java.", if so change the package name. This is happening considering your bundle name is colliding with java system file names.

The accepted answer did non resolve the issue, hence posting what worked for me.

Fault/Issue: While trying to run my awarding as a Java awarding or as a Spring kick application, I am getting below error

A JNI mistake has occurred, delight check your installation and try again. A Coffee exception has occured.

every bit well as getting this error on console Exception in thread "main" java.lang.UnsupportedClassVersionError: com/instance/demo/IocApplication has been compiled past a more than recent version of the Java Runtime (class file version 55.0), this version of the Coffee Runtime only recognizes course file versions up to 52.0

What is the Root cause?

The reason for this fault is that

the Code is getting compiled on a higher version, in my example, it is version 11.. and
the code is getting executed on a lower version, in my case information technology is version viii.
ie: Java(JDK) compiled code on xi , where as JRE version is 8.

Where did I configure JDK 11 and JRE 8 ?

I am using SpringToolSuite (STS). When I created the project, the JRE Arrangement library in the build path, which got added is the default JRE library version of 8 (one.8) But When I go to Projection -> properties -> Java Compiler -> Compiler Compliance Level, it is by default having a selected version of xi

Solution:

Project -> properties -> Coffee Compiler -> Compiler Compliance Level

Set the Compiler Compliance Level to 1.8 That's it. Now y'all are compiling your code in 1.eight and executing the compiled code with a JRE 1.8.

All is non work for me only In one case I delete the ".metadata" & ".recommenders" of workspace and also delete the "bin" and "setting" folder and then afterward I re-import the same project so It worked for me.

<classpathentry kind="con" path="org.testng.TESTNG_CONTAINER"/>

I think this happen considering the name of your class is the same proper name of another class in the JDK . Assistance eclipse to determine which one you are trying to run by selecting the package your class is in . Get to run configuration select the projection and the master class.

When yous press the search push to select the main class, y'all will find options that have the aforementioned name just different package, select your class.

I faced a similar problem and than got the solution in the package proper name. I kept the package name as java.nuts. In the panel I got a hint for that as it clearly said Prohibited package proper name. And so I inverse package proper name and information technology worked.

Using gradle the following also worked for me:

Parcel Explorer -> Right Click project -> Gradle -> Refresh Gradle Projection

In Netbeans eight.0.2:

Right click on your package.
Select "Properties".
Go to "Run" pick.
Select main class by browsing your form name.
Click the "Ok" push.
