   <!-- Test time only --> <dependency> <id>ashcroft</id> <version>0.1</version> </dependency>

2. Edit project.properties to enable Ashcroft:

   # make sure the ashcroft jar you're using is available in the remote repository (it is at codehaus) maven.repo.remote=http://www.ibiblio.org/maven,http://dist.codehaus.org # install ashcroft as your security manager maven.junit.jvmargs=-Djava.security.manager=com.thoughtworks.ashcroft.runtime.JohnAshcroft # make sure the jvm forks, otherwise the jvmargs will be ignored maven.junit.fork=true
