Camel does not build with maven 2.1.0
-------------------------------------
Key: CAMEL-1731
URL: https://issues.apache.org/activemq/browse/CAMEL-1731
Project: Apache Camel
Issue Type: Bug
Affects Versions: 1.6.1
Reporter: Guillaume Nodet
It barfs with the following error:
[INFO] The projects in the reactor contain a cyclic reference: Edge between
'Vertex{label='org.apache.camel:camel-buildtools'}' and
'Vertex{label='org.apache.camel:camel-buildtools'}' introduces to cycle in the
graph org.apache.camel:camel-buildtools --> org.apache.camel:camel-buildtools
The problem is that the parent pom defines the checkstyle plugin and defines a
dependency on buildtools. So when maven tries to buid buildtools, it has a
dependency on itself because it is inherited from the parent pom.
A fix would be to define a "parent" module. The root pom would not define the
checkstyle plugin, but this definition would be in the parent module. The
buildtool module would directly inherit from the root pom, while all other
modules inherit from the "parent" pom.
