RE: Trouble with build - maven build hangs and CPU uasge for java 100%!

If you run maven with -X and see the command-line output, could you try the scalac command directly and see if it's also pegging your CPU?

I suspect there may be some kind of issue with the Scala compiler, and have therefore cross-posted this message to the Scala list.

To the Scala list: the issue occurs when trying to build the Apache  Incubator's ESME project - the source can be accessed via SVN at  http://svn.apache.org/repos/asf/incubator/esme/trunk/server and built with a "mvn compile". We'd be glad of any pointers as to why the build nails the CPU at 100% for so long...

use -Dmaven.scala.displayCmd=true instead of -X (less verbose, only
the commande line)

I gave it a go:

Missing:
----------
1) net.sf.jsr107cache:jsr107cache:jar:1.0

Try downloading the file manually from:
http://maven.apache.org

Then, install it using the command:
mvn install:install-file -DgroupId=net.sf.jsr107cache
-DartifactId=jsr107cache -Dversion=1.0 -Dpackaging=jar
-Dfile=/path/to/file

Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=net.sf.jsr107cache
-DartifactId=jsr107cache -Dversion=1.0 -Dpackaging=jar
-Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

Path to dependency:
1) org.apache.esme:esme-server:war:0.2.3-SNAPSHOT
2) org.openid4java:openid4java:jar:0.9.3
3) net.sf.ehcache:ehcache:jar:1.3.0
4) net.sf.jsr107cache:jsr107cache:jar:1.0

----------
1 required artifact is missing.

for artifact:
org.apache.esme:esme-server:war:0.2.3-SNAPSHOT

from the specified remote repositories:
compass-project.org (http://repo.compass-project.org),
scala-tools.org (http://scala-tools.org/repo-releases),
scala-tools.org.snapshots (http://scala-tools.org/repo-snapshots),
internal (http://192.168.106.29:8080/archiva/repository/internal)

Thanks, David - this POM change cut the Maven build elapsed time from 2'45" to 1'22" for me.

Cheers,
