And the finale of my day was spending an hour + trying to figure out why a Java program with outside dependency loading runs in Eclipse but not CMD....

- Intellij community
- gradle

@SortOfTested thats not cmd? I can run it fine in Eclipse

Maven?

@yellow-dog no I'm trying to run the app, bills is fine. I can't run it properly from cmd

@billgates oh youre linking a jar?

@yellow-dog yea but somehow not working... Probably a Java issue. Default Java is JRE, for the main app I set JAVA_HOME to the JDK folder but I think the third party component still decides to use the JRE. So app starts but then get a ClassNotFound error when the lib is used.

Somehow when running from eclipse though, everything uses the JDK

@billgates
Gradlew will spew the results at you along with the deep error.

@SortOfTested so instead of calling Java -cp I call Gradle -cp?

@billgates
Gradle has build deps file that will save you manually specifying the classpath.

If you're manually calling javac, it's tedious. If the jar is present java -cp /path/to/jar:/path/to/jar2:. MyApp.java should work.

Yeah, manually linking jars is an awful idea, set up a maven or gradle project and just let them do the magic

@yellow-dog I got it! But now I feel stupid...

I set CLASSPATH var. Thought it was like PATH, some system var that java always pickup.

Just I guess with the -cp flag it doesn't... So yes the fix was obvious....
