Crashes while running "Maven In Five Minutes"
If I follow the steps listed here (https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html) : mkdir scratch; pushd scratch; mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false; cd my-app; mvn package; mvn clean dependency:copy-dependencies package; mvn site I get several crashes. The first of which is: [INFO] - [ERROR] COMPILATION ERROR : [INFO] - [ERROR] Source option 5 is no longer supported. Use 6 or later. [ERROR] Target option 1.5 is no longer supported. Use 1.6 or later. Even if I fix that error I get another error later.

Looks very useful to me, not only for the maven-release-plugin. If You don't mind, I'd invest a little time to transfer it to a new library and extend it for my use cases. That would be great. I guess I was working on it before I had to switch to JPMS/Project Jigsaw support. Since then focus was on keeping all our ~100 subprojects running on more Java versions. The maven-release-plugin is not dead. There are more things that should be improved for 3.0.0, but based on business value I need to focus on other topics. Will definitely work on it again in the future! Robert @Anton: DecentXML is an interesting library, too. I'll surely remember this one. @Matthieu: Besides some other use cases, we basically need this for a migration of a very huge/complex project setup into a new project layout. For this, (re)calculate our projects (including dependencies, properties etc) and we need to continuously transfer changes between old and new project layout for a transition period.

We need to (programmatically) do several changes on Maven POMs, e.g. adding and removing dependencies and properties. Currently we're using the MavenXpp3Reader and MavenXpp3Writer classes to read and write the pom.xml files, but in the output files, all comments are removed, the XML nodes are reordered and formatting (indentations, empty lines) is lost. Does anybody know a way how to read and write POM files without loosing formatting ordering and comments?
