Hi,
I have not been able to get generate-features-xml to work a very simple
example, and I didn't find any luck on Google/Bing/this forum for a solution
(exception this one,
http://mail-archives.apache.org/mod_mbox/felix-users/201011.mbox/%3CAANLkTinOoV6brGc7ahpxBJRQ1L96+kFD8XKN-bgAJ+=w...@mail.gmail.com%3E,
which does not provide a solution.)
Here is my simple test:
...
<dependencies>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.8</version>
</dependency>
</dependencies>

<plugins>
<plugin>

<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/bundles</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.karaf.tooling</groupId>
<artifactId>features-maven-plugin</artifactId>
<version>2.2.0</version>
<executions>
<execution>

<goals>

</goals>
<configuration>
<bundles>bundles.properties</bundles>
<outputFile>${project.build.directory}/features.xml</outputFile>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
Here is the error:

[ERROR]
The example provided at
http://karaf.apache.org/manual/2.1.99-SNAPSHOT/developers-guide/features-maven-plugin-generate.html
does not work either. There seems to be a typo with the goal.
Can someone please help pointing out what I did wrong? No body seem to have
this problem, so I must have a stupid error somewhere, but I really run out
of resources. Your help is greatly appreciated.
Regards,
- Triet
