Building the metadata mapping module with maven fails for me. First, I’m seeing this error message: > [ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4.1:single (zip-owa) on project metadatamapping-owa: Assembly is incorrectly configured: null: Assembly is incorrectly configured: null: [ERROR] Assembly: null is not configured correctly: Assembly ID must be present and non-empty. [ERROR] → [Help 1] This appears to be because the assembly.xml does have an tag. (See: [[MASSEMBLY-517] Assembly fails with empty id element now - ASF JIRA](https://issues.apache.org/jira/browse/MASSEMBLY-517)) I add an tag to the assembly.xml (just something random like “test”) and I get farther, but then run into this: > [ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.4:copy (include-owa) on project metadatamapping-omod: Unable to find artifact.

I have just compiled it with Java 8 and all was well. Which version of Java are you using? ---

Hmm… I am using Java 7. This module _should_ still compile on Java 7, correct? Take care, Mark ---

I have just compiled it again successfully with Java 7. Could it be something in your .m2 folder? ---

The issue is we haven’t declared a version of the assembly plugin so the build may fail on systems using a newer version, which requires assembly Id. The other issue is that we forgot to add a dependency on owa to the omod pom. Let me fix all that. ---

I decided to simplify the setup and use the latest version of SDK for packaging. Fixed in: [https://github.com/openmrs/openmrs-module-metadatamapping/commit/a208833dfdefd65cc821cba7a9220463df5c086c](https://github.com/openmrs/openmrs-module-metadatamapping/commit/a208833dfdefd65cc821cba7a9220463df5c086c) @mogoodrich, let me know if it works for you now. ---

It worked thanks @raff!
