engines.properties and maven shade plugin

[Johannes Daxenberger]

Hi,

I'm experiencing strange behavior when using DKPro Lab with the maven shade plugin. The packaged standalone jar fails with "Exception in thread "main" java.lang.IllegalArgumentException: No engine registered for type ..." - as a result of the content of META-INF/lab/engines.properties (it misses the ExecutableTaskEngine). I would assume that this is a bug caused by the face that this file is defined both in dkpro-lab-core and in dkpro-lab-uima-engine-simple (and potentially elsewhere), but written to a single file in the standalone jar - apparently overwritten.

Maybe I am also using the shade plugin incorrectly, that's why I am writing here rather than opening an issue.

This is for dkpro-lab 0.11.0.

Shade-plugin configuration (v. 2.4.3):

<!-- Merge the uimaFIT configuration files -->

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">

<resource>META-INF/org.apache.uima.fit/fsindexes.txt</resource></transformer>

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">

<resource>META-INF/org.apache.uima.fit/types.txt</resource></transformer>

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">

<resource>META-INF/org.apache.uima.fit/typepriorities.txt</resource></transformer>

</transformers>

<filters>

<filter>

<artifact>*:*</artifact>

<excludes>

<exclude>META-INF/*.SF</exclude>

<exclude>META-INF/*.DSA</exclude>

<exclude>META-INF/*.RSA</exclude>

</excludes>

</filter>

</filters>

Thanks,

Johannes

Hi,

you need to define an appending transformer for "META-INF/lab/engines.properties" in the same way as it is being done for the uimaFIT files.

That makes sense and solves the issue :)

Thanks!
