How to use cached files as workspace relative path

GitLab CI/CD
1

Hi All,

I have two jobs as below:
1.build_libs: build project in ${workspace_loc/libs/libxx/} and will output lib file ${workspace_loc/libs/libxx/bin/libxx.a}
2. build_apps: build project in ${workspace_loc:/apps/appmain/} with dependency library is libxx above (${workspace_loc/libs/libxx/bin/libxx.a})

If I define artifacts attribute in build_libs job, output lib will be keep in ${workspace_loc/libs/libxx/bin/libxx.a}

However, If I don’t define artifacts attribute but define only cached attribute in build_libs job, output lib will be clean after the job is done. Then, build_apps job will fail with error "can not resolve simple libbrary ${workspace_loc:/libs/libxx/bin/libxx.a}

My ci as below:

stages:

  • init
  • build
  • package

.common
