Monday April 14, 2008 Fixing OutOfMemory errors with Ant
Ever get this while running an Ant task like wsdl2java or javac?
java.lang.OutOfMemoryError: Java heap space
The solution is pretty simple. Increase the amount of memory for the Ant JVM. On Linux, you could issue the following in a Shell command:
export ANT_OPTS="-Xms512m -Xmx512m"
Windows would be similar in a command prompt before calling Ant:
set ANT_OPTS="-Xms512m -Xmx512m"
Of course, make sure you have that much memory available first. If not, try a smaller value like 256m.
