Description Stanislav Ochotnicky 2013-11-13 16:32:50 UTC 
plexus-compiler fails to build from source due to unresolvable dependencies for requires generator which fails the build to prevent incorrect package dependencies[1]. 

Snippet from build.log:

Exception: Following dependencies were not resolved and requires cannot be generated. Either remove the dependency from pom.xml or add proper packages to BuildRequires:
org.apache.maven.plugins:maven-gpg-plugin:::UNKNOWN
org.codehaus.plexus:plexus-compiler-test:::UNKNOWN

Rebuilding with the 2.2-6 patch I get

Indeed, it pulled in itself in pre-build:

DEBUG util.py:281:    plexus-compiler.noarch 0:2.2-5.el7

It's a loop because plexus-compiler buildrequires plexus-compiler-extras, which in turn requires mvn(org.codehaus.plexus:plexus-compiler-api), which is provided by plexus-compiler. 

How did you work around this to get it to build without an explicit Buildrequires: plexus-compiler?
Comment 9 Mikolaj Izdebski 2014-01-30 12:18:02 UTC 
You can try temporarly patching fragment file with sed (see below). Once you build plexus-compiler, rebuild it without this workaround.

sed -i -n '/<autoRequires>/{:a;N;/<\/autoRequires>/{p;b;};/>UNKNOWN</{:b;n;/<\/autoRequires>/{b;};bb;};ba;};p' %{buildroot}%{_mavendepmapfragdir}/*

Right after %mvn_install. It worked. Thanks!
