未设置Android项目Gitlab-ci.yml JAVA_HOME

Question

我目前正在尝试创建一个.gitlab-ci.yml文件，在该文件中自动构建Android Studio项目。我的GIT回购中的文件结构如下：

the_app
.gitlab-ci.yml
README.md

我的.gitlab-ci.yml看起来是这样的：

image: jangrewe/gitlab-ci-android
variables:
ANDROID_COMPILE_SDK: "30"

before_script:
- export GRADLE_USER_HOME=$(pwd)/.gradle
- apt-get update -y && apt-get install wget -y  
build:
script:
- cd ./ISSD_application
- chmod +x ./gradlew
- ./gradlew assembleDebug
artifacts:
paths:
- app/build/outputs/

但现在我得到的错误是：

ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

用于Android项目的Java安装在我的计算机上，而不是在GIT repo中。如何正确设置JAVA_HOME变量以便构建项目？

Answer 1

实际上，图像中没有设置JAVA_HOME，但java二进制文件位于/usr/bin/java下。

您可以按照设置GRADLE_USER_HOME的方式设置JAVA_HOME，在before_script部分：

before_script:
- export GRADLE_USER_HOME=$(pwd)/.gradle
- export JAVA_HOME="/usr/bin/java"
- apt-get update -y && apt-get install wget -y
