JAVA_HOME is not working in maven
After struggling for almost a day, I found out that maven is not reading the $JAVA_HOME
from either of
~/.bashrc
~/.bash_profile
~/.profile
but it reads $JAVA_HOME
from ~/.mavenrc
So finally, when I added
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_141.jdk/Contents/Home
in ~/.mavenrc
then got output
mvn -v
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=1024m; support was removed in 8.0
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-03T15:39:06-04:00)
Maven home: /usr/local/Cellar/maven/3.5.0/libexec
Java version: 1.8.0_141, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_141.jdk/Contents/Home/jre
Default locale: en_CA, platform encoding: UTF-8
OS name: "mac os x", version: "10.12.6", arch: "x86_64", family: "mac"
maven reads JAVA_HOME from ~/.mavenrc. Add path for JAVA_HOME to ~./mavenrc and source it.
$ vim ~/.mavenrc
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .mavenrc
To fixed it, update the JAVA_HOME like following :
$ vim .bash_profile
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .bash_profile
Run Maven again :
$ mvn -version
On Ubuntu
I faced a similar problem. I configured $JAVA_HOME
in /etc/environment
like JAVA_HOME=PATH_TO_JDK
for example JAVA_HOME=/home/max/jdk1.8.0_144
Careful with
- White space after path declaration
JAVA_HOME=/home/max/jdk1.8.0_144[[_NO_WHITE_SPACE_AFTER_DECLARATION]]
- Don't put any quotes, e.g.
JAVA_HOME="/home/max/jdk1.8.0_144"
- Don't put
/bin
, e.g.JAVA_HOME=/home/max/jdk1.8.0_144/bin
<- This is wrong
