Classes not found during runtime.

Weissmoon · April 2, 2019

I am trying to add libraries to the minecraft runtime using the Jar-in-jar method. The jar files are added into the "META-INF/libraries/" folder in the compile jar. The jars extract to "run/mods/1.12.2". The latest.log contains these lines:

I have tried adding the {entry}.meta in src/main/resources/(diesieben07), META-INF/libraries/(Forge Documentation), and not including the file. All methods result the same.

Has this happened to anyone before?

Cadiboo · April 6, 2019

Until recent Forge versions mods couldn’t package any libraries under the Apache package (for security reasons?). You’re using a pretty old forge version.

Weissmoon · April 8, 2019

I updated forge version to 1.12.2-14.23.5.2768. I still have the same error.

Weissmoon · April 8, 2019

The jars are in META-INF/libraries/ and the version of forge I have is 1.12.2-14.23.5.2768.

Weissmoon · April 8, 2019

I cannot, there is an error with the upload.

Weissmoon · April 8, 2019

I have a jar available on curseforge

Weissmoon · April 8, 2019

I have added META-INF/libraries/commons-math3-3.2.jar.meta containing:

Maven-Artifact: org.apache.commons:commons-math3:3.2

The result is the same.

Weissmoon · April 17, 2019

here is a link to the newest version

Weissmoon · April 18, 2019

I have discovered that even after updating forge versions past 1.12.2-14.23.5.2758 apache libraries are still failing to load.

That’s still a very old version
