PoC: Use Eclipse b3 aggregator to create maven library from Trace Compass Eclipse plug-ins (CTF)

[bhufmann]

What it does

• releng: add b3 aggregator for generating a maven repository for CTF
  This project creates an maven repository with ctf.core and ctf.parser.
  The location of the generated maven repository is under target/final/
• example: create an example project that uses maven dependencies only for CTF parsing
  The maven dependencies are generated using b3 aggregator of project:
  releng/org.eclipse.tracecompass.aggregation/.

See link below for more details
https://wiki.eclipse.org/CBI/aggregator/manual

How to test

• First run the aggregator:

cd releng/org.eclipse.tracecompass.aggregation
mvn clean install

The resulting maven repository is stored under releng/org.eclipse.tracecompass/org.eclipse.tracecompass.aggregation/target/final

• Fix TODOs doc/org.eclipse.tracecompass.maven.example/pom.xml and MyTest.java to build and run example.

cd doc/org.eclipse.tracecompass.maven.example/
mvn clean install

• Run the example

mvn exec:exec

Follow-ups

Proof-of-concept. Possible follow-ups

• Deploy the CTF parser plugin to maven central.
• Update and deploy other Trace Compass plug-ins to maven central (e.g. tmf.core) by adding relevant plug-in IDs to releng/org.eclipse.tracecompass.aggregation/tracecompass.aggr
