If the projects cannot compiled by Eclipse, i.e. contains compilation errors, the tool should not create a JAR file/bundle (if one of the builders fails).
Add for Builder-Plugin description note that the project with this nature added has precedence (or not, depending on the Local repo order) over bundles from repos with lower priority.
Also add uninstallation instructions, esp. note that "Local" repository is not cleaned up after plugin is uninstalled
