Maven environment variables (2.7)
A number of environment variables must be set for optimal Maven performance. For UNIX operating systems one typically modifies a startup file like ~/.bash_login to set and export shell variables while Mac users typically set and export environment variables in .bash_profile
. For Windows, go to Start -> Control Panel -> System -> Advanced -> Environment Variables
and set your Maven environment variables via the GUI.
Set the MAVEN_HOME
environment variable to point to the base directory of your Maven installation and add the Maven /bin
directory to your PATH
variable:
Variable |
Unix/Mac |
Windows |
---|---|---|
MAVEN_HOME |
|
|
PATH |
|
|
Windows: append string to the end of the Path
system variable
MAVEN_OPTS
Maven does not read JAVA_OPTS
on start up, resulting occasionally in "Out of Memory" errors when building Sakai. To assure sufficient memory allocation during builds, you should add a MAVEN_OPTS
environment variable as defined below. For UNIX operating systems one typically modifies a startup file like ~/.bash_login to set and export shell variables while Mac users typically set and export environment variables in .bash_profile
. For Windows, go to Start -> Control Panel -> System -> Advanced -> Environment Variables
and set JAVA_HOME
via the GUI.
export MAVEN_OPTS='-Xms512m -Xmx1024m -XX:PermSize=64m -XX:MaxPermSize=128m'
