/**
* Abstract base plugin which takes care of the common stuff usually needed by maven IDE plugins. A plugin extending
* AbstractIdeSupportMojo should implement the setup() and writeConfiguration() methods, plus
* the getters needed to get the various configuration flags and required components. The lifecycle:
*
*
* *** 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
*
