将我的库上传到 jitpack 时出错

Question

Am trying to publish my app into jitpack from git, the library working locally well in android java, but not working once uploaded to jitpack.

jipack log is in red color icon.

After implementing the library dependency on a test app, the test app is not showing classes from the library

*build.gradle(:app)

Answer 1

I have faced exactly the same problem.

I suspect the JitPack is not currently supporting Android Gradle Plugin 7.4.0 (Gradle 7.5)

My solution is to step back to Android Gradle Plugin 7.3.1 (Gradle 7.4)
