Arbi Sookazian [http://community.jboss.org/people/asookazian] replied to the discussion "build path not set correctly after importing from svn for mavenized Seam project" To view the discussion, visit: http://community.jboss.org/message/535000#535000 -------------------------------------------------------------- I upgraded to 3.1.0.GA JBT. So I think I nailed down the root cause of why m2e can't accommodate my projects in terms of proper classpath/build path.  Ultimately it comes down to the Maven Dependencies list being incomplete/wrong I guess but not sure how to fix this as my Seam application consists of two higher-level pom.xml (i.e.this is multi-module scenario consisting of two project with multi-modules and one depends on the other for services, API calls, etc.)  Thus, I typically run 'mvn clean install' on two pom's, first model, then GUI. I have two parent pom.xml files.  One is dependent on the other (the model pom has the DAO, domain/entity classes, etc).  These are apparently two independent projects when I do a svn checkout as Maven project. So the following .classpath file for one of the mvn modules in the non-model project (it's called GUI which depends on Model packages/classes, etc.) does not have references to the model modules/projects so these packages and classes are unrecognizable by the compiler: <?xml version="1.0" encoding="UTF-8"?> <classpath>     <classpathentry kind="src" output="target/classes" path="src/main/java"/>     <classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources"/>     <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5"/>     <classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER"/>     <classpathentry kind="output" path="target/classes"/> </classpath> When I run 'mvn eclipse:eclipse', the .classpath contents for this module/project change to the following which "fixes" the compiler resolution errors b/c of the classpathentry entries below for the cis.crud.dao, cis.crud.domain, etc which are apparently missing when m2e creates the .classpath file: <classpath>   <classpathentry kind="src" path="src/main/java" including="**/*.java"/>   <classpathentry kind="src" path="src/main/resources" excluding="**/*.java"/>

got from Jason Van Zyl to a (now closed) JIRA issue I opened regarding this same topic in this thread: *The maven-eclipse-plugin is not supported. Any problems are with  configurators so report what is missing. You won't be able to sue mvn  eclipse:eclipse with M2Eclipse 1.0.* -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/535000#535000] Start a new discussion in JBoss Tools at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
