Ilya Buziuk :
Building this maven project used to work just fine for quite a while (6 month), but today while executing mvn clean install the build start hanging every single time (tried with different versions of mvn including the latest 3.5.0 and against both openJDK & Oracle JDK - result is the same)

Is it some weird deadlock issue ? Thanks in advance!
UPDATE Actually the build does not hang forever (only 20 - 25 mins). Still it is not clear what is the reason
ingyhere :
Maven 3.5.x has some pretty terrible bugs, namely:
What is specifically happening is that if you are building a project with submodules or multiple projects, Maven 3.5.x sporadically locks up when downloading duplicate dependencies. Example: Let spring-expression-4.3.5.RELEASE be a dependency of two or more project POMs. It's downloaded into the Maven Repo by project 1 at ".m2\repository\org\springframework\spring-expression\4.3.5.RELEASE\spring-expression-4.3.5.RELEASE.jar" (of course, with the POM and checksum files). When project 2 goes to check/download the same dependency in the same location, it locks up for 20 minutes and then reports "0 B" was downloaded in the logs.
Until the Maven team addresses this issue in the 3.5.x releases, we pulled back to Maven 3.3.9 and the problem vanished. (NOTE: This was regularly reproducible at the same point in dependency resolution in our project.)
