I see a strange behavior that I believe is a bug. If I use the following config: ```auto language: java jdk: oraclejdk11 install: - echo $JAVA_HOME - false ``` then the outcome is: ```auto $ java -Xmx32m -version openjdk version "11.0.2" 2019-01-15 OpenJDK Runtime Environment 18.9 (build 11.0.2+9) OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode) $ javac -J-Xmx32m -version javac 11.0.2 install.1 0.00s$ echo $JAVA_HOME /usr/local/lib/jvm/openjdk11 0.00s$ false ``` But if I add `arch: arm64` to the config: ```auto language: java jdk: oraclejdk11 arch: arm64 install: - echo $JAVA_HOME - false ``` then `JAVA_HOME` is empty: ```auto $ java -Xmx32m -version openjdk version "11.0.5" 2019-10-15 OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.5+10) OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.5+10, mixed mode) $ javac -J-Xmx32m -version javac 11.0.5 install.1 0.02s$ echo $JAVA_HOME 0.01s$ false ``` ---

Thanks for the report. I took a quick look. We are installing `adoptopenjdk-*-hotspot` package [https://github.com/travis-ci/travis-build/blob/0d3f1f908897605ec66c0d04b2e150741c4381dc/lib/travis/build/bash/travis\_install\_jdk.bash#L45-L57](https://github.com/travis-ci/travis-build/blob/0d3f1f908897605ec66c0d04b2e150741c4381dc/lib/travis/build/bash/travis_install_jdk.bash#L45-L57) I believe the expectation was that these packages would set necessary environment variables, but probably that was wrong. We will look into it. ---

Curiously, > **[Installation | AdoptOpenJDK](https://adoptopenjdk.net/installation.html?variant=openjdk11&jvmVariant=hotspot#linux-pkg)** > > AdoptOpenJDK provides prebuilt OpenJDK binaries from a fully open source set of build scripts and infrastructure. Supported platforms include Linux, macOS, Windows, ARM, Solaris, and AIX. does not mention `$JAVA_HOME` for Linux installation. We can guess the value based on files at hand, and it would go something like this: ```auto f=$(which javac) while [[-L $f]]; do f=$(readlink $f); done export JAVA_HOME=${f%/bin/*} ``` The result is something like this: [https://travis-ci.org/BanzaiMan/travis\_production\_test/builds/641393626#L890](https://travis-ci.org/BanzaiMan/travis_production_test/builds/641393626#L890) Could you add the snippet above in your build and see if that meets your needs? Thanks. ---

Thank you for the workaround! It helps! ---

Did that work for you? ---

Yes! But I think it would be better if it is consistent in both environments. ---

Not clear to me that would be possible, given that we use different mechanisms to install the Java packages. ---

Is that solicitation for a patch? 🙂 ---
