java.lang.NoClassDefFoundError:
Lorg/sonatype/plexus/build/incremental/BuildContext;
Hi,
I'm in the middle of developing an integration server for several month now.
Of course the system embedds maven which did work rather good with maven
2.2.1 and even the beta builds of maven 3. Since the release of 3.0 and even
3.0.1 my own MavenEmbedder class (basically something like this
http://java.net/projects/hudson/sources/svn/show/trunk/hudson/lib/maven-embedder)
does not work any more. If I try to build an test project with my embedder
i get an NoClassDefFoundError:
java.lang.NoClassDefFoundError:
Lorg/sonatype/plexus/build/incremental/BuildContext;
at java.lang.Class.getDeclaredFields0(Native Method) ~[na:1.6.0_22]
at java.lang.Class.privateGetDeclaredFields(Class.java:2291) ~[na:1.6.0_22]
at java.lang.Class.getDeclaredFields(Class.java:1743) ~[na:1.6.0_22]
at
com.google.inject.spi.InjectionPoint.getInjectionPoints(InjectionPoint.java:649)
~[sisu-guice-2.9.1-noaop.jar:na]
[...]
I can provide the complete stacktrace if necessary.
The only strange thing I can find in my logs is the following that gets
logged right before the error occurs:
17:06:21.845 [main] WARN d.b.a.i.b.maven.MavenLoggingAdapter - The POM for
org.apache.maven.shared:maven-filtering:jar:1.0-beta-4 is invalid,
transitive dependencies (if any) will not be available, enable debug logging
for more details

Ok with this debugging information I was able to debug into the maven
execution and see where the validation really fails. For some reason the
MavenExecutionRequest had its system properties not populated. I looked what
the hudson embedder is doing regarding the system properties and did the
same:
Properties systemProperties = request.getSystemProperties();
systemProperties.putAll(System.getProperties());
systemProperties.putAll(getEnvironment());
not that getEnvironment() is a method i copied from the hudson embedder
which basically wraps every environment variable into a property prefixed by
"env.".
So whats the real deal? How is one supposed to populate the system
properties of an execution request? Am I missing something?

I am still hunting this one down. For some reason I do not seem to be able to
get proper debug output from maven. I really would like to know why this
keeps preventing me from getting the proper dependencies for the resources
plugin included:
10:54:43.051 [main] WARN d.b.a.i.b.maven.MavenLoggingAdapter - The POM for
org.apache.maven.shared:maven-filtering:jar:1.0-beta-4 is invalid,
transitive dependencies (if any) will not be available, enable debug logging
for more details
as far as "enable debug logging" is considered I finally managed to get more
output. this is the relevant debug output:
11:06:05.621 [main] WARN d.b.a.i.b.maven.MavenLoggingAdapter - The POM for
org.apache.maven.shared:maven-filtering:jar:1.0-beta-4 is invalid,

Hi,
thanks for the hint. When including this dependency for some reason I seem
to run into major classloader issues. Here is the output/exception of the
maven execution:

I fear that the main reason for this to fail is that the pom for

extract more info from maven on what exactly is invalid.

Hi,
Try with adding the following dependency :
<dependency>
<groupId>org.sonatype.plexus</groupId>
<artifactId>plexus-build-api</artifactId>
<version>0.0.6</version>
</dependency>
HTH,
