------------------------------------

             Summary: Test scope dependency adds compile dependency to library 
which was excluded on the compile dependency path
                 Key: MNG-5690
                 URL: https://jira.codehaus.org/browse/MNG-5690
             Project: Maven
          Issue Type: Bug
            Reporter: Tobias Oberlies


Consider two libraries with the following, simplified dependency graph:
{noformat}
+- org.apache.cxf:cxf-rt-transports-local:jar:2.7.5
   +- org.apache.cxf:cxf-api:jar:2.7.5:compile
      +- org.apache.geronimo.specs:geronimo-javamail_1.4_spec:jar:1.7.1:compile

+- org.apache.cxf:cxf-rt-frontend-jaxrs:jar:2.7.5
   +- org.apache.cxf:cxf-api:jar:2.7.5:compile
      +- org.apache.geronimo.specs:geronimo-javamail_1.4_spec:jar:1.7.1:compile
{noformat}

The following situations work as expected:
# When adding a test dependency to cxf-rt-transports-local in my war project, 
the geronimo-javamail library *is not* assembled into the war.
# When adding a compile dependency to cxf-rt-frontend-jaxrs, the 
geronimo-javamail library *is* assembled into the war.
# When adding a compile dependency to cxf-rt-frontend-jaxrs with an exclusion 
of the geronimo-javamail, the library *is not* assembled into the war.

The unexpected behaviour occurs when combining the dependencies from point 1 
and 3 (with the test dependency being listed above the compile dependency). In 
this case, the geronimo-javamail libary *is* assembled into the war, although I 
only have a test scope dependency to it.

The following pom.xml reproduces the problem:
