Missing entries in New Project Example dialog

Description of problem:

When running https://github.com/lgrossma/jbosstools-integration-tests/blob/maven/tests/org.jboss.tools.maven.ui.bot.test/src/org/jboss/tools/maven/ui/bot/test/conversion/MaterializeLibraryTest.java via maven, creating a new Example (File -> New -> Example), selecting Jboss Tools Project Examples results in page with multiple projects you can choose from, but the list is missing "Jboss Maven Archetypes" entry which results in test failure

Workaround: Start test manually from eclipse via Reddeer

Steps to Reproduce

1. If you don't want to start all tests, comment out everything except MaterializeLibraryTest.class from https://github.com/lgrossma/jbosstools-integration-tests/blob/maven/tests/org.jboss.tools.maven.ui.bot.test/src/org/jboss/tools/maven/ui/bot/test/MavenAllBotTests.java

2. Get to the

jbosstools-integration-tests/tests/org.jboss.tools.maven.ui.bot.test

3. run

mvn clean verify -U -PITests -Pdownload-jbt -DskipTests=false

 
4. Test fails because entry in list is missing

 
Possible cause is probably missing entry in MANIFEST.MF file, but can't figure out which one is missing
