Jenkins build failed due to missing android SDK

Question

As the title says my jenkins build fails due to not finding the android sdk dispite it being located in the environments path.

Here is the console logs

As u can see, the path clearly has android_home set correctly.

I am trying to build this via gradle in jenkins.

This is teh pre executed shell commands i have configured this job to do

export ANDROID_HOME=/Users/lmnapp/android-sdk-macosx export ANDROID_SDK=/Users/lmnapp/android-sdk-macosx/platforms export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$ANDROID_HOME export AVD_NAME=jenkinsGoogleApi18_1  echo displayPath echo .... echo ....  echo $PATH 

Answer 1

Fixed it.

1. Go to Jenkins > Manage Jenkins > Configure System
2. Check "Environment variables"
3. add name: ANDROID_HOME, value -> your android sdk dir
4. click "add"
5. SCROLL DOWN CLICK SAVE

Answer 2

The problem is that you are exporting the ANDROID_HOME environment variable in an "Execute shell" step. Once the shell step has completed, that environment is gone — the variables will not be carried over to subsequent build steps.

If you were executing everything, including Gradle, in a single build step, it would work, e.g.

export ANDROID_HOME=/foo/bar/sdk ./gradlew clean assembleProductionRelease 

But since you're using the Gradle plugin as a separate build step, the environment variables are no longer available.

Exporting the environment variable globally via the Jenkins config as you have done in your own answer is one way to solve this, though you can also use the EnvInject plugin to inject environment variables during a build. Variables set up using this plugin will be available to all build steps.

For a build machine, the best practice would be to minimise the amount of manual setup required, like installing the Android SDK and hardcoding environment variables into the server config.

I can recommend adding the Android SDK Manager plugin to your Gradle build — it will automatically install the Android SDK plus any build dependencies for you.
