GitLab CI：无法设置 JAVA_HOME

Question

I am running git-lab server with Ubuntu 14 I am trying to compile a build on git-lab Ci but for some reasons I keep getting the same error over and over again:

ERROR: JAVA_HOME is set to an invalid directory: /usr/lib/jvm/java-7-openjdk-amd64/jre Please set the JAVA_HOME variable in your environment to match the location of your Java installation.

No matter how I change the path of JAVA_HOME it is always the same results. I have 4 folders inside the JVM folder:

java-8-oracle
java-7-openjdk-amd64
java-1.7.0-openjdk-amd64
default-java

But again no matter which directory I set the path to it is always the same result.

Here is my .gitlab-ci.yml file:

 before_script:
- export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre
- export ANDROID_HOME="/opt/android-sdk"
- chmod +x gradlew

dev:  
  script:
  - ./gradlew assembleDebug

What could be the cause of this error?

Answer 1

Try to change your .gitlab-ci.yml to this:

before_script:  
  - export ANDROID_HOME="/opt/android-sdk"
  - export JAVA_HOME="/usr/lib/jvm/java-1.7.0-openjdk-amd64"
  - chmod +x gradlew

dev:  
  script:
    - ./gradlew assembleDebug

Answer 2

You can try removing chmod +x gradlew from before_script and move it to the main script :

before_script:
- export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre
- export ANDROID_HOME="/opt/android-sdk"

dev:  
  script:
  - chmod +x ./gradlew
  - ./gradlew assembleDebug

Answer 3

I know this issue might have been fixed already. But here is how I fixed mine.

Use case:

After I updated Java on my 3 environmennts(Dev, Staging, and Prod), everithing worked just fine on Dev and Staging. But, for some reasons, the pipeline job in charge of deployment on production kept sending this error: "ERROR: JAVA_HOME is set to an invalid directory: C:/Program Files/Java/jdk1.8.0_171. Please set the JAVA_HOME variable in your environment to match the location of your Java installation." My JAVA_HOME was set to the correct path.

Fix: 0. make sur you Java_Home is properly set up. Fir windows users, something like C:/your jdk root folder/ (do not add /bin folder). 1. Clear the runner caches in gitlab. 2. Restart the gitlab-runner service on your deployment server.

I hope that could help someone else.
