Maven: Using Oracle Archetypes with Maven in Eclipse

1. Go here: https://community.oracle.com/docs/DOC-894569
2. Download this file: https://maven.oracle.com/archetype-catalog.xml
1. It will ask for your OTN login, of course.
2. If you don't download it, you will not be able to use it.
3. During archetype selection, click Configure... next to the Catalog drop-down.
4. Add Local Catalog...
1. Adding a remote catalog is not working because of the HTTP Basic auth.
5. Choose the recently downloaded file.
6. Do the next-next-finish magic.
7. Voilá.

For the exact version of the archetype, take a ook inside: https://www.oracle.com/content/secure/maven/content/com/oracle/weblogic/archetype/basic-webapp/maven-metadata.xml

Compiling Atlassian JIRA and having hamcrest-all 1.2 maven dependency resolution problem

So you are compiling Atlassian JIRA from source, and the compilation fails with:
Failed to execute goal on project atlassian-secure-random: Could not resolve dependencies for project com.atlassian.security:atlassian-secure-random:jar:3.2.1: Could not find artifact org.hamcrest:hamcrest-all:jar:1.2 in central (https://maven.your-corporation.com/artifactory/repo)

Of course, you started wandering around teh Internet, and was shocked to see, that https://code.google.com/p/hamcrest/ only knows about hamcrest-all 1.1 and 1.3... wtf?!

The missing version is hosted by Atlassian. You should set your stuff up to look up https://maven.atlassian.com/content/groups/public/ also.
Look for Philipp Steinwender's answer at https://answers.atlassian.com/questions/192831/maven-dependency-com-atlassian-jira-plugins for a maven settings.xml fragment.
