Hi

Yes it does take time to do a clean rebuild ;) And you need to increase =
the memory settings on Maven to let it be able to compile it all.

The snapshorts is deployed on a public maven server
http://activemq.apache.org/camel/download.html

Apache snapshots
http://people.apache.org/repo/m2-snapshot-repository

http://people.apache.org/repo/m2-snapshot-repository/org/apache/camel/apa=
che-camel/

So you can add the apache m2 snapshot in your pom.xml and you are off to =
go.

    <repository>
      <id>apache.snapshots</id>
      <name>Apache Development Snapshot Repository</name>
      <url>http://people.apache.org/repo/m2-snapshot-repository</url>
      <releases>
        <enabled>false</enabled>
      </releases>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
    </repository>

Subject: Re: Can not compile examples from 1.4 snapshot

I just tried to compile the snapshot from source. The first thing I must =

say ... it takes ages. So this is sure no way to get people to test the=20
snapshots.
The other thing is that I am getting an out of memory error at the camel =

cxf example while compiling.

I think it would be better if you could deploy the snapshot to a maven=20
repository. So people could use the binary download wwithout compiling=20
all themselves.
In any case there should be a description somewhere that the examples=20
from the binary distro will only run if you first compile from source.=20
For me this was not clear at the start.

Greetings

Christian
