mvn changes PageRankVertex.java

Hi,

I'm trying to build giraph. I start hadoop 1.1.2 and run "mvn test" on a 
clean git clone. Then I get errors.

[ERROR] Failed to execute goal 
org.apache.maven.plugins:maven-compiler-plugin:3.0:compile 
(default-compile) on project giraph-core: Compilation failure: 
Compilation failure:
[ERROR] 
/home/emre/git/giraph/giraph-core/target/munged/main/org/apache/giraph/benchmark/PageRankVertex.java:[1,1]

[ERROR] -> [Help 1]

When I looked at this file, I see that mvn causes a change on the 
comments like below. Is this a bug or am I doing something wrong?

[emre@localhost giraph]$ git diff

Seems like they were the results of the unstable code and missing jar 
files on the web. I got a recent copy and used skipTests parameter and 
could successfully build giraph without passing the tests.

Hi,

I fixed the modified file problem I mentioned in my previous post with a 
trick modifying the line /* to /** and it didn't happen.

Now I'm getting the following error:

[ERROR] Failed to execute goal on project giraph-examples: Could not 
resolve dependencies for project 
org.apache.giraph:giraph-examples:jar:0.2-SNAPSHOT: Failure to find 
org.apache.giraph:giraph-core:jar:tests:0.2-SNAPSHOT in 
http://repo1.maven.org/maven2 was cached in the local repository, 
resolution will not be reattempted until the update interval of central 
has elapsed or updates are forced -> [Help 1]

Seems like giraph packages are not available on any maven repos on the 
web. I removed giraph-examples from the modules in pom.xml now I got

[ERROR] Failed to execute goal on project giraph-accumulo: Could not 
resolve dependencies for project 
org.apache.giraph:giraph-accumulo:jar:0.2-SNAPSHOT: Failure to find 
org.apache.giraph:giraph-core:jar:tests:0.2-SNAPSHOT in 
http://repo1.maven.org/maven2 was cached in the local repository, 
resolution will not be reattempted until the update interval of central 
has elapsed or updates are forced -> [Help 1]


What can I do?
