Not really.
Well, you could put your stuff in $JAVA_HOME/lib, but that is certainly 
not standard

You either set environment variable CLASSPATH or you add -classpath when 
running java.

ant is just a make for java

I had a quick look at it and basically you'll do like this:

1. Build the C++ stuff so that you have protoc built
2. Run:
src/protoc --java_out java/src/main/java -Isrc 
src/google/protobuf/descriptor.proto
3. cd java/src/main/java
4. javac com/google/protobuf/*.java
5. jar cf protobuf-java-2.3.0.jar com/google/protobuf/*.class (jar name 
derived from pom.xml)
6. cp protobuf-java-2.3.0.jar /whereever/you/want/your/jar
