Usage

From source file:org.eclipse.gemini.blueprint.test.provisioning.internal.LocalFileSystemMavenRepository.java

/**
 * Initialization method It determines the repository path by checking the
 * existence of <code>localRepository</code> system property and falling
 * back to the <code>settings.xml</code> file and then the traditional
 * <code>user.home/.m2/repository</code>.
 * // www  .java 2  s.  c  o  m
 * <p/> This method is used to postpone initialization until an artifact is
 * actually located. As the test class is instantiated on each test run, the
 * init() method prevents repetitive, waste-less initialization.
