Has anyone created a Gradle build script to create a custom Karaf assembly?
I work on project whose application is developed on a network with Internet access, but runs on a standalone computer (no Internet access). We currently create a custom Karaf assembly using Maven and then install the assembly on the the standalone computer. The project has to move its development environment to a network without any Internet access. Running Maven on this isolated network is problematic, so we are switching to Gradle. We have successfully built and tested the individual modules that go into the custom Karaf assembly. However, we are having trouble creating a Gradle build script that creates the custom Karaf assembly. The specific problems that we are having are: - identifying dependencies and copying them to the system directory - identifying the three Karaf library jar files and copying them to the lib directory - creating a feature file as a separate artifact - creating a jar file that only contains resources (for branding) I was hoping that someone had some experience that could provide some insight and be able to answer questions. I've attatched the pom.xml that we are currently using with Maven so that it is clear what we need to do in Gradle. Thanks, Tim
