The openwire generator is executed by the activemq-client project when the "
openwire-generate" build profile is enabled and the "antrun:run" goal is
executed (according to the comments in the pom):
mvn -P openwire-generate antrun:run
This runs a complex script that appears to ultimately boil down to the
following process:
- Scan all java files in the activemq-client src folder
- For all of the files that contain the comment "openwire:marshaller":
- Generate a class with the same name plus the suffix *Marshaller*
- Place the generated class in the packace
org.apache.activemq.openwire.v<version-num>
Looking through the code, it appears that all of the sources that feed this
process are in the org.apache.activemq.command package.
Note this same process is used to generate C++ and C# code - at least, I
see references to such.
For more details of the process itself, see the activemq-openwire-generator
project. JavaGeneratorTask is the main class.
