[tycho-user] Help with ChmodAction failure during build of RCP applicati

["Tom Bryan (tombry)" <tombry@xxxxxxxxx>]

I'm using Tycho 0.24 and Java 8 to build an Eclipse RCP application.

I've been setting the versions for dependencies in our MANIFEST.MF, feature.xml, and .product files.  Once I got all of that set and compiling correctly, I started getting a new error from the packaging step of the build.  I was on Tycho 0.22, but I tried upgrading to Tycho 0.24 to see whether it was just a bug with an older version of Tycho.  Same error.  I've already spent a few hours investigating, but I still have no idea what the problem is.  Worse, I have no idea what I changed that could have triggered this problem. 

At this stage, all of the plug-ins for my project have been compiled and installed in the local maven repository.  This is just another build step that packages our RCP app for various platforms.   I think that the relevant part of my pom.xml is

 

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-deploy-plugin</artifactId>

<version>2.7</version>

<configuration>

<skip>true</skip>

</configuration>

</plugin>

<plugin>

<groupId>org.eclipse.tycho</groupId>

<artifactId>tycho-p2-director-plugin</artifactId>

<version>${tycho-version}</version>

Here's the error: 

[INFO] Installing product com.cisco.vmmaestro.cml.rcp for environment linux/gtk/x86 to /home/jenkins/jenkins/jobs/CML_DEV_product_package_build/workspace/com.cisco.tools.cide/build/com.cisco.vmmaestro.cml.repo/target/products/com.cisco.vmmaestro.cml.rcp/linux/gtk/x86

The action chmod failed - file /home/jenkins/jenkins/jobs/CML_DEV_product_package_build/workspace/com.cisco.tools.cide/build/com.cisco.vmmaestro.cml.repo/target/products/com.cisco.vmmaestro.cml.rcp/linux/gtk/x86/icon.xpm does not exist

I've looked at my older builds to see that icon.xpm did used to get created somehow in that location.  We've never done that step explicitly, so I assumed that it was built into some Tycho build step based on the product's icon definition for the linux platform.  

Just to resolve any questions about having the wrong path, I added our cml.xpm file to the same project as the .product file and this  pom.xml file.  That way, my .product file can simply say 

   <launcher name="CML">

      <linux icon="cml.xpm"/>

But even after that change, I'm getting the same error.  Running with the -X option didn't really provide any additional information about what's going on during the previous steps that should have copied/renamed cml.xpm to the icon.xpm that Tycho cannot find.

Any suggestions about how to troubleshoot this problem?

Thanks,
