Maven does not work

[ianvieira]

After installing Java 7, following @russalex instructions in the #49 issue, Maven does not work. Installing via apt-get doesn't work because requires the openjdk (that doesn't work via apt-get), so I installed manually. Trying to run mvn clean install, nothing happens. Here is the strace for it: http://pastebin.com/hB8zQMkG.
I tryied to do a symlink in the WSL user home directory to avoid any error about the filesystem but I have the same error.

Is the strace output similar on Native Ubuntu? I'm mostly wondering if the "/etc/mavenrc" file exists (near the end of your provided strace).

[ianvieira]

I created the "/etc/mavenrc" manually, and the "~/.mavenrc" also. But still does not work.

Maven can now be installed via apt-get (since #49 was resolved) but it still freezes and does nothing. and can't be quit either

Same here, this time with openjdk7 installed via apt-get and latest 14366 build. The java process has to be killed with task explorer as it fully uses one core and does not respond to ctrl+C.

Any chance to get it fixed? There is multiple tickets around java, some of them are closed, but anything more complex that hello world doesn't seem to work :(
I tried different versions of java from different sources, with "default-jdk" I was at least able to get mvn -version, but nothing more :(

It works for me on build 14901. With maven 3 downloaded from http://www-eu.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz, default-jdk (version 7) & git from apt. My rather complicated application (an application server) fully compiles and tests can run (It's clearly slower than on native Windows on the same machine, but I don't care).

Many thanks to the WSL team.

Be great to understand how you got this working @marcanpilami
first mvn -v didn't work, but after setting JAVA_HOME, it works with the following output, but everything else just hangs

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T16:41:47+00:00)

@khowling : on build 14946, Ubuntu 16.04.1. Just do:

cd ~
sudo apt install openjdk-8-jdk-headless
wget http://wwwftp.ciril.fr/pub/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
tar -xzf apache-maven-3.3.9-bin.tar.gz
export PATH="$PATH:~/apache-maven-3.3.9/bin"
cd YOUR_PROJECT_PATH
mvn clean install

Bonus: now with JDK 8 and not 7 anymore. Getting better and better.
