+/**
+ * Abstract base plugin which takes care of the common stuff usually needed by maven IDE plugins. A plugin extending
+ * AbstractIdeSupportMojo should implement the <code>setup()</code> and <code>writeConfiguration()</code> methods,
+ * plus the getters needed to get the various configuration flags and required components. The lifecycle:
+ * 
+ * <pre>
+ *       *** calls setup() where you can configure your specific stuff and stop the mojo from execute if appropriate ***
+ *       - manually resolve project dependencies, NOT failing if a dependency is missing
+ *       - compute project references (reactor projects) if the getUseProjectReferences() flag is set
+ *       - download sources/javadocs if the getDownloadSources() flag is set
+ *       *** calls writeConfiguration(), passing the list of resolved referenced dependencies ***
+ *       - report the list of missing sources or just tell how to turn this feature on if the flag was disabled
+ * </pre>
