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
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
repository. So people could use the binary download wwithout compiling
all themselves.
In any case there should be a description somewhere that the examples
from the binary distro will only run if you first compile from source.
For me this was not clear at the start.
Greetings

Hi ,
If you are running the example for source code, you'd better run "mvn
install -Dtest=false" from the root directory to install the snapshot
artifacts in your local maven repository first.

I have tried to run the examples from the 1.4 snapshot. Like
described in
http://activemq.apache.org/camel/running-examples.html
mvn exec:java
I get the following error:
Cannot find parent: org.apache.camel:camel-parent for project:
null:examples:pom:null for project null:examples:
It seems the examples need a parent pom that is not existing in the
distribution. So probably this can be fixed by adding the parent pom
to the distribution. Though I think the concept of a parent pom for
examples is a bad thing in general.
As people often want to start their own project with the example code
I think each example should be able to exist on it´s own and so it
should not need a parent pom.
Is this a good idea?
