Github user xyztdanid4 commented on the issue: https://github.com/apache/metron/pull/952 @merrimanr As we agreed yesterday I did the required changes in the pom xml-s. I had to update the node dependency of the projects, otherwise the build was failed, cause one of the dependencies was dependent on node8. There is no equivalent command to npm --prefix in yarn, so I updated the readme to just cd into that directory where the install step is required. When we build the metron-alert project (angular4), there was an error, mainly because angular4 uses AOT as default builder strategy. I fixed this by addig env=prod to the package json.
