Bug 634046 – After emerging dev-util/bazel-0.5.2 there should be advice to set JAVA_HOME

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description Rabbe Fogelholm 2017-10-11 20:30:32 UTC]

Typing `bazel help' produces 

    Couldn't find java at '/usr/libexec/bin/java'.

This can be fixed by setting JAVA_HOME, e.g. like this,

    export JAVA_HOME=`java-config --jdk-home`

I suggest that an "emerge message" is added for this, to make it easier
getting started, especially since there is no manpage and `bazel --help`
does not work either.

Output of `emerge --info'

Normally JAVA_HOME is set by /etc/profile.d/java-config-2.sh which is installed by sys-apps/baselayout-java. Do you have that file?

[Comment 3 Zac Medico 2017-10-30 03:13:30 UTC]

Since bazel already has a java-config dependency from the java-pkg-2 eclass it inherits, you probably just need to do this:

  source /etc/profile

I suppose would would suggest to do that with an elog message on the first install, possibly using the readme.gentoo-r1 eclass.
