Java – Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.4.3:test (default-test) on project smrr: There are test failures

When I run maven test, java.lang.OutOfMemoryError happens. I google it for solutions and have tried to export MAVEN_OPTS=-Xmx1024m, but it did not work.

Setting the Xmx options using MAVEN_OPTS does work, it does configure the JVM used to start Maven. That being said, the maven-surefire-plugin forks a new JVM by default, and your MAVEN_OPTS are thus not passed.

To configure the sizing of the JVM used by the maven-surefire-plugin, you would either have to:

• change the forkMode to never (which is be a not so good idea because Maven won't be isolated from the test) ~or~
• use the argLine parameter (the right way):

In the later case, something like this:

<configuration>
  <argLine>-Xmx1024m</argLine>
</configuration>

But I have to say that I tend to agree with Stephen here, there is very likely something wrong with one of your test and I'm not sure that giving more memory is the right solution to "solve" (hide?) your problem.

one thing that may cause this problem is that in your project in a POM file required java or maven version is set. you should find it... but how ? maybe you couldn't find any enforcer in your project like me ... (I had the same problem and I became confused because enforcer plugin was not defined in my projects POMs, so I couldn't find it).

enforcer plugin is in your "effective pom" and you should check it. Effective pom is a configuration file made from super pom + project pom. maven use this configuration file to execute the relevant goal. It helps developers to specify minimum configuration detail in his/her pom.xml. Although configurations can be overridden easily.

For showing your effective pom there are 2 ways: 1- use maven command, run this command :

 mvn help:effective-pom

2- use your IDE : in Maven window right click on your project node and select show effective POM(it depends on your IDE).

after you find what your forces are you can find it in your project and change it. for me, My effective POM had enforcer plugin which its requireMavenVersion rule for using Java was 1.8. so I changed my project JDK version to 1.8 and luckily the problem was solved.

I hope this answer could help you.
