Re: [aspectj-users] [aspectj plugin] weaving jars to other projects + 3rd party libaries not found in those projects
|
Hi Simone,
thx for the fast reply. The plugin part from the project where the
aspect is located is the following:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>compile</goal>
</goals>
</execution>
</executions>
<configuration>
<source>1.6</source>
<target>1.6</target>
<verbose>true</verbose>
<outxml>false</outxml>
<showWeaveInfo>true</showWeaveInfo>
<aspectDirectory>src/main/aspectj</aspectDirectory>
<testAspectDirectory>src/test/java</testAspectDirectory>
</configuration>
</plugin>
And the next plugin part is in another project where I inject the
compiled aspects into:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<executions>
<execution>
<phase>compile</phase>
<goals>
<goal>compile</goal>
</goals>
</execution>
</executions>
<configuration>
<source>1.6</source>
<target>1.6</target>
<verbose>true</verbose>
<outxml>false</outxml>
<showWeaveInfo>true</showWeaveInfo>
<aspectLibraries>
<aspectLibrary>
<groupId>wsmx</groupId>
<artifactId>wsmx-securitymanager</artifactId>
</aspectLibrary>
</aspectLibraries>
</configuration>
</plugin>
The error trace:
...

Hi Michael,
can you post the <plugin> part of the pom.xml where you are
configuring the AspectJ mojo?
Also, could you post the stacktrace of the exception?

Hi,
I'm using the maven plugin for aspectj, but I think most of you use
that too, so I write to this mailinglist ;)
I have several projects (each project is a component for the whole
system) and I apply already compiled aspects to them. Everything
works fine until I access a 3rd party library from the aspect, for
example I call a factory class or make an instance. If I do that, I
get a java.lang.NoClassDefFoundError execption, so the classloader
cannot find the library.
I tried several things: First I tried to include the library directly
into the compiled aspect lib. The second thing I tried was to include
that library in the project where I injected the aspect code using
the compiled aspect lib. Unfortunately none of both worked for me and
the java.lang.NoClassDefFoundError remains.
My question is, how do you access within an aspect a 3rd party
library? I mean where can I put those libaries into, in order that
the classloader can find it, in each proejct where I weave the
compiled aspects?
Thank you very much for your help, I hope someone can help me!
Best regards
Rogger
