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:

Quote

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.

change wording

Has this happened to anyone before?

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.

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

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

I cannot, there is an error with the upload.

I have a jar available on curseforge

Edited April 8, 20196 yr by Weissmoon

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.

here is a link to the newest version

https://drive.google.com/open?id=1ibtpyOBOdEFkZCx1twAZFPp-94SFi2MS

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

3 hours ago, Weissmoon said:

1.12.2-14.23.5.2758

That’s still a very old version
