[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-8208) Improve how annotation processors are setup/detected via maven/m2eclipse

[ https://issues.jboss.org/browse/JBIDE-8208?page=com.atlassian.jira.plugin... ] Snjezana Peco commented on JBIDE-8208: -------------------------------------- I have tried to create a project based on the org.jboss.weld.archetypes:jboss-javaee6-webapp:1.0.1.Beta2 archetype and noticed two issues: 1) CDI and JSF facet aren't added when creating a project (a bug in the JBoss Maven configurators. They don't check transitive dependencies.). See JBIDE-8252. 2) JDT Maven configurator breaks annotation processing so that it removes the target/generated-sources/annotations directory (annotation processor source directory) from the classpath. This can be reproduced as follows: - create a javaee6 project and enable annotation processing as Dan Allen described in https://issues.jboss.org/browse/WELD-835?focusedCommentId=12577274&pa... - right-click the project, select Maven>Update Project Configuration Annotation processing won't work because the Maven JDT Configurator has removed the target/generated-sources/annotations directory from the classpath. There are several issues related to the way m2eclipse configures a classpath. See https://issues.sonatype.org/browse/MNGECLIPSE-2367 The problem can be solved by right-clicking the project, selecting Properties>Java Compiler>Annotation Processing, unchecking Enable annotation processing, clicking Apply, checking Enable annotation processing and clicking Apply again. However, calling Maven>Update Project Configurator will break annotation processing again. A solution would be to create a maven configurator (or change the maven hibernate configurator) that would check for existing the org.hibernate:hibernate-jpamodelgen dependency and if exists, the configurator would enable annotation processing and would add the correspondent factory path. In this case, .factorypath and .settings, Dan added to the archetype, wouldn't be necessary. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
