gitlab-ci 多java版

Question

I have an question about gitlab-ci, my java project should support different java version because these is necessary and i struggle to setup gitlab-ci correctly. My gradle builder works on my personal computer but on gitlab or jitpack it did even fail the job. My Project have these structure

Protectionlib (ProjectName):
   Core (Java8):
      gradle.build
   LocalLibary (Java8):
      gradle.build
   PlotSquaredv3 (Java8):
      gradle.build
   PlotSquaredv4 (Java8):
      gradle.build
   PlotSquaredv6 (Java17):
      gradle.build

There is my gitlab repo i try to build: https://gitlab.com/Ste3et_C0st/protectionlib/-/tree/master on my computer the job is builded successful, i have defined the used java version in the gradle.build over sourceCompatibility & targetCompatibility.

I hope someone can help me about that problem.

Answer 1

in your .gitlab-ci.yml the line export GRADLE_USER_HOME=pwd/.gradle is not correct, you can just remove the line.
see https://docs.gradle.org/current/userguide/build_environment.html#sec:gradle_environment_variables

that line is mixing system-home with local gradle project cache
