[jira] [Commented] (FELIX-5327) SCR Plugin: FileNotFoundException
in multi-module Maven reactor build in 2nd module
[ https://issues.apache.org/jira/browse/FELIX-5327?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426561#comment-15426561 ]
Konrad Windszus commented on FELIX-5327:
----------------------------------------
This happens only when configuring the scr plugin like this {{...;destdir=target/classes}} (it is necessary for Maven to overwrite the destdir, because the default is the folder {{bin}}) (https://github.com/apache/felix/blob/trunk/tools/org.apache.felix.scr.bnd/src/main/java/org/apache/felix/scrplugin/bnd/SCRDescriptorBndPlugin.java#L245).
When configuring it like this in your pom.xml it works
{code}
...;destdir=${project.build.outputDirectory}...
{code}
It would be nice if relative paths would be better supported in Maven, but I am not sure this is easily possible because the plugin must also be supported outside Maven.

> Key: FELIX-5327
> URL: https://issues.apache.org/jira/browse/FELIX-5327
> Project: Felix
> Issue Type: Bug
> Components: SCR Tooling
> Affects Versions: scr bnd plugin 1.5.0
> Reporter: Konrad Windszus
>
> In a multi-module Maven build the scr bnd plugin tries to write the bind methods into the wrong file. Instead of {{<current maven module directory>/target/classes/...}} it tries to use {{<root maven module directory>/target/classes/...}}.
> The funny thing is that this only happens with the 2nd Maven module containing components, for the first Maven module it works correctly.
> So it seems that the scr bnd plugin is not always using the correct base path.
> The exception when this occurs looks like this
> {code}
> [ERROR] Bundle <some bundle>:<some version> : Got unexpected exception while analyzing:org.apache.felix.scrplugin.SCRDescriptorException: Unable to add methods to <Fully qualified class name of SCR Component>
