"Invalid maximum heap size" when running Maven
heap-memory, java, jvm, maven
Solution
User @med_alpa had the right suggestion in my case (Windows):
I resolved the same issue on windows executing this command on windows command line : set MAVEN_OPTS=-Xmx1024M -XX:MaxPermSize=256M
So make sure to not put quotes around the value you set for MAVEN_OPTS
Problem
I'm having problems setting up maven. I'm using windows 7 64 bit with 4 GB of RAM. I get this error when trying to run mvn: ``` Invalid maximum heap size: -Xmx512m. Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. ``` Here are my user variables: ``` JAVA_HOME=C:\Program Files\Java\jdk1.7.0_55 M2=%M2_HOME%\bin M2_HOME=C:\Program Files\Apache Software Foundation\apache-maven-3.2.1 MAVEN_OPTS=-Xms256m -Xmx512m Path=%M2%;%JAVA_HOME%\bin ```
