Hi I am working on weka api in Eclipse Mars. Everything was fine until i wrote a class for LinearRegression, just then Eclipse started giving JNI error. Now other classes runs fine but when i try to run LinearRegression class the error pops up.
The first error is Error: A JNI error has occurred, please check you installation and try again followed by JVM launcher error "A java exception has occurred". And then a list of errors

I tried searching all over but couldn't find a solution that works, Anybody had the same issue and got it resoled please provide the solution
enthusiast,
Just add
testImplementation('org.junit.platform:junit-platform-launcher:1.5.2')
to the dependencies section in build.gradle file, refresh gradle (on eclipse, on the context menu of the project > Gradle > Refresh Gradle Project). You should be able to run tests one by one.
Happy coding

A detailed answer for my approach is highly appreciated.
You error suggest that you're using a lower JVM version than the one the application was build. Try upgrading your java version

Could not find the main class: com.ibm.jinwoo.heap.HeapAnalyzer. Program will exit.
Has anyone else experienced this and know how to fix it?
type java --version does the version agree with 51.0
refer to stackoverflow.com/questions/10382929/…
you may need to install the latest jdk, or you can export the JAVA_HOME for the IBM JDK and add $JAVA_HOME/bin to your path
I need some help! I have re-installed Eclipse and the latest GWT SDK 2.5.1/App Engine SDK 1.8.4 and my previously working app is not working any more. I cannot find the way out.
As far as I could figure out it has something to do with the maven dependency. Can I remove it? How?
I believe it is simple. Please help!

I have found the solution: in the build path I had included libraries I did not really need anymore. After cleaning of the project the app was working as expected.
PS: thank you Chris for your help!
You can try changing the 'Persistence' of GAE from JPA2 to JPA1. It worked for me.
