[jira] Created: (MNG-919) Installation with symlinks
Installation with symlinks
--------------------------
Key: MNG-919
URL: http://jira.codehaus.org/browse/MNG-919
Project: Maven 2
Type: Improvement
Components: maven-core
Versions: 2.0-beta-1
Environment: Linux/Unix
Reporter: Alex Wood
Attachments: m2-failed-start.txt
When trying to install the Maven 2 beta, I followed the instructions available at http://maven.apache.org/maven2/download.html
However, I did not set my $PATH to include a reference to the Maven 2 directory. I prefer to keep my $PATH very short and so I put a symlink to m2 in /usr/local/bin. When I tried to start Maven 2, I received the following message:
Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/classworlds/Launcher
After looking at the m2 shell script, I noticed the reference to $M2_HOME was not being set correctly. After setting that variable correctly, Maven 2 started without a problem.
I've attached the output of bash -x for a failed startup. It looks to me like the problem is in this section
## resolve links - $0 may be a link to maven's home
PRG="$0"
saveddir=`pwd`
# need this for relative symlinks
PRGDIR=`dirname "$PRG"`
cd "$PRGDIR"
while [ -h "$PRG" ] ; do
[...]
Since my symlink was in my path, PRG got set to just "m2" which fouled the rest of the script. Using 'which' might help here.

Alex
