Sonar analysis gives out of memory error, should I increase JVM heap space of Ant or Sonar server?

问题

I am analysing a large project in Sonar and get the following error:

[sonar:sonar] 03:55:39.511 INFO  p.PhasesTimeProfiler - Execute decorators...

Should I increase the java heap space of the running Sonar server, or the Ant target executing the Sonar job?

回答1:

As you can see from the stack trace, the Ant starts the Sonar analysis, so you should increase the heap space for the VM the Ant runs in.

This is a very similar question BTW: How to increase Sonar Java heap space

For command line Ant usage

Quote from the answer by Mark O'Connor on the other question:

The Sonar ANT task executes as part of ANT so you need to set the JVM heap using the standard ANT environment parameter. For example:

export ANT_OPTS=-Xmx256m

Remarks:

this is for Linux, for Windows, use the set command
this is strictly for the heap space. for Permgen, use -XX:MaxPermSize=<desired amount>

This is an even more similar question: Build Failed java.lang.OutOfMemoryError: Java heap space

For Eclipse IDE

Quote from the article http://soenkerohde.com/2008/06/change-eclipse-ant-settings-when-you-run-out-of-memory/

In Eclipse open menu: Run->External Tools->Open External Tools Dialog…

Select the build script you want to change on the left

Select the JRE tab on the right

Set the following as VM arguments: -Xms768m -Xmx1024m -XX:MaxPermSize=512m

For IntelliJ Idea

This forum thread is useful: ANT build java heap space

Quote from the answers:

Please make sure that you increased heap in a correct place. You need to click 'Properties' button in IDEA's Ant tool window and edit 'Maximum heap size (Mb)' field there.

Also, from the IntelliJ Idea page: Increasing Memory Heap

Quote from the article:

The memory heap of the build process is independent of IntelliJ IDEA memory heap, and is released after the build process is complete.

To increase a memory heap: Open the Build File Properties dialog box. In the Maximum heap size field, type the required amount of memory.

For Jenkins Continuous Integration and Ant build

This question is useful : How to use the Java Options in jenkins ant build tool to set ANT_OPTS

Quote from the answer:

Set the JAVA OPTIONS as -Xmx512m -XX:MaxPermSize=256m only without the ANT_OPTS=

For Maven builds, this article is of use: How to increase maven heapspace in hudson builds

Navigate to your hudson job,

click Configure,

scroll down to the Build section, and

click the Advanced button.

Enter this into MAVEN_OPTS: -Xmx512m -XX:MaxPermSize=128m
