A set of common Java utilities for use in projects.

Warwick Utils

This is a set of (mostly Java) tools that can be used as dependencies from other projects.

Setting up for development

Go to Import -> Existing projects in Eclipse, select the "modules" folder and add all the projects there. Once that's done, you can add the top-level project.

Pushing a release onto Nexus

Examples are for command line in UNIX.

First, set the version number:

$ mvn versions:set -DnewVersion=$(date +%Y%m%d)
$ mvn versions:commit

This should set the-current-date in all the pom.xml files.

Commit and push to master; you can then run the manual goal from the Bamboo build once it's built.

Multiple versions on the same day

If you get a message like this:

[ERROR] Failed to execute goal [...] Failed to deploy artifacts: Could not transfer artifact [...] from/to nexus [...] Return code is: 400, ReasonPhrase:Bad Request

It probably means that the artifact already exists on Nexus, and Nexus doesn't support overwriting of artifacts with the same version. The easiest way to fix this is to add an hour/minute component to your versioning:

$ mvn versions:set -DnewVersion=$(date +%Y%m%d-%H%M)
$ mvn versions:commit

You should then be able to deploy.

Generating distributables without pushing to Nexus

The dist profile will put JARs in a dist directory off the project root:

$ mvn -Pdist

Installing into the local Maven repository for testing

$ mvn versions:set -DnewVersion=20190114-SNAPSHOT
$ mvn install -DskipTests
