JAVA_HOME not set

Hello,

I am trying to install bazel, but this gives me following error:

$ pacaur -S bazel
[...]
which: no javac in (/home/philipp/.local/bin:/usr/lib/colorgcc/bin/:/usr/lib/ccache/bin/:/usr/local/sbin:/usr/local/bin:/usr/bin:/opt/cuda/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl)

Try 'readlink --help' for more information.
INFO: You can skip this first step by providing a path to the bazel binary as second argument:

?  Building Bazel from scratch
ERROR: JDK not found, please set $JAVA_HOME.
==> ERROR: A failure occurred in build().
    Aborting...
:: failed to build bazel package(s)

Any suggestions how to fix this?
Thanks in advance!

Re: JAVA_HOME not set

Have you checked whether javac exists on your system? It's supposed to be /usr/bin/javac → /usr/lib/jvm/default/bin/javac. Both of them appear to be in your $PATH, so there is no need to set $JAVA_HOME.

Re: JAVA_HOME not set

If you have installed the jdk8-openjdk, jre8-openjdk, java-openjfx and icedtea-web packages it should work all the files should be included in those packages - do have these installed on your system?

Re: JAVA_HOME not set

add in this before ./compile.sh

export JAVA_HOME=/usr/lib/jvm/default

Re: JAVA_HOME not set

With Java 7:

$pacman -S jdk7-openjdk
$archlinux-java set java-7-openjdk
INFO: You can skip this first step by providing a path to the bazel binary as second argument:

ERROR: JDK version (1.7) is lower than 1.8, please set $JAVA_HOME.
==> ERROR: A failure occurred in build().

Obvious not working, but Java 8 also fails:

BTW:

$JAVA_HOME

was not set by any of

archlinux-java

commands.

I have also exported the JAVA_HOME enviroment variable,

export JAVA_HOME=/usr/lib/jvm/default

Compile warnings vanish, but segfault is still there.

Re: JAVA_HOME not set

that folder /usr/lib/jvm/default/bin/ needs a lot more files, looks like something went wrong with your installation .

$ pacman -Qo /usr/bin/javac
/usr/bin/javac is owned by java-environment-common 2-2
$

please post pacman -Qs java

Re: JAVA_HOME not set

The first one tells you that the application requires JDK 1.7, so you need to compile it with Java 8 (jdk8-openjdk)'s compiler. That seems reasonable so far.

The second one is a bit odd - I just built the `bazel` package on my own system, and noticed the following:

  • From a quick glance (I've lost the full output), there appears to be no Java source file being compiled - are you building the same package as I was?

  • It creates directories in my home directory (notably ~/.cache, despite my $XDG_CACHE_HOME being set to a different value) - that's not a problem with the package, but rather with whatever is running as part of the build process - and it's definitely not polite to create files outside the build directory, so I would already advise against its use just on principle.

Also, no, there is no need to set $JAVA_HOME - that's only if you want to set a temporary installation location for the JRE/JDK. What's the output of this command?

pacman -Qkk jdk8-openjdk

I have unsetted the JAVA_HOME, this works now!
