maven-surefire-plugin

I am using maven with the jacoco plugin to generate code coverage metrics. I am having some difficulty in configuring the surefire plugin with the java options required by the jacoco plugin. I've seen some answers about this already on Stack Overflow but something is not working for me. I have a multi-module project, and one of my modules configures the surefire plugin as follows: foo/pom.xml : <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <argLine>-XX:MaxPermSize=512m</argLine> </configuration> </plugin> </plugins

I have a multi-module maven project with both integration and unit tests in the same folder (src/test/java). Integration tests are marked with @Category(IntegrationTest.class) . I want to end up with the following setup: If I run mvn install , I want all tests to compile, but I do not want to execute any. If I run mvn test , I want all tests to compile, but execute only unit tests. If I run mvn integration-test , I want to compile and execute all tests. The important point is, I want this configured in the pom.xml without any extra commandline arguments. Currently I came up with the following

I've a Maven build in which I use the SureFire plugin to run some unit tests, and the FailSafe plugin to run some integration tests. I would like a way to run just the FailSafe plugin's tests. It's not a good solution for me to add different profiles or anything in the pom, because it's a multimodule build and I don't want to have to edit every module's pom. There are skip.tests and maven.test.skip and skipTests which stop all tests, and skipITs , which stops only the failsafe plugin. So, is there a command-line flag for Maven like skipITs , but instead with the functionality of "onlyITs"? I

Using JUnit 4.8 and the new @Category annotations, is there a way to choose a subset of categories to run with Maven's Surefire plugin? For example I have: @Test public void a() { } @Category(SlowTests.class) @Test public void b() { } And I'd like to run all non-slow tests as in: (note that the -Dtest.categories was made up by me...). mvn test -Dtest.categories=!SlowTests // run non-slow tests mvn test -Dtest.categories=SlowTests // run only slow tests mvn test -Dtest.categories=SlowTests,FastTests // run only slow tests and fast tests mvn test // run all tests, including non-categorized So

Recently coming to a new project, I'm trying to compile our source code. Everything worked fine yesterday, but today is another story. Every time I'm running mvn clean install on a module, once reaching the tests, it crashes into an error: [INFO] --- maven-surefire-plugin:2.18.1:test (default-test) @ recorder --- [INFO] Surefire report directory: /lhome/code/recorder/target/surefire-reports [INFO] Using configured provider org.apache.maven.surefire.junitcore.JUnitCoreProvider [INFO] parallel='none', perCoreThreadCount=true, threadCount=0, useUnlimitedThreads=false, threadCountSuites=0,
