Curiously,

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.
