Hi,
So the last couple of days the master branch wouldn't build on my systems:
[INFO] Apache CloudStack Framework - IPC ................. FAILURE [1.874s]
...

[INFO]
------------------------------------------------------------------------
[ERROR] Failed to execute goal

So I'm running Ubuntu 12.04.1 on all my systems (laptop, desktop,
servers) and this is the maven information:
wido@wido-desktop:~$ mvn -v
Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.6.0_27, vendor: Sun Microsystems Inc.
Java home: /usr/lib/jvm/java-6-openjdk-amd64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.2.0-38-generic", arch: "amd64", family: "unix"
wido@wido-desktop:~$
Now, that Java version is old, I know, but it's the openjdk version
which is in Ubuntu 12.04's repositories right now.
I downloaded Java 7:
wido@wido-desktop:~/repos/cloudstack$ JAVA_HOME="/opt/jdk1.7.0_15" mvn -v
Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.7.0_15, vendor: Oracle Corporation
Java home: /opt/jdk1.7.0_15/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.2.0-38-generic", arch: "amd64", family: "unix"
wido@wido-desktop:~/repos/cloudstack$
With that Java version the master branch builds just fine.
What I want to discuss which version of Java we support.
I'd say we support the LTS version of any major release of CentOS or Ubuntu.
I also understand that Java 6 is pretty old, so what do we do?
