[ https://issues.jboss.org/browse/JBIDE-19536?page=com.atlassian.jira.plugi... ] Vsevolod Golovanov commented on JBIDE-19536: -------------------------------------------- I think, my problem is not really related to this task... I've attached [^workspace_jbds9_endless_building_loop.rar]. The problem began to reproduce when I configured metamodel generation (APT processing) in the root project. This triggered m2e to consider the ear project to contain java sources too (this is not the case with JBDS8): it adds Java Nature, considers the whole ear project directory to be its sources, and sets the output directory to be "bin" inside the ear project directory. The output directory is thus inside the "source" directory. I think, this is what creates the endless building loop. So the problem seems to be: * Our weird configuration results in ear project having maven-compiler-plugin and maven-processor-plugin configured. * The newer m2e versions started adding Java Nature to such ear projects. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
