How does one build the java JRE from source (src.zip in JDK)? -

-

surprisingly enough couldn't find answer question.

i trying rebuild java jre source. obtain java jre source extracting src.zip file in jdk.

after making changes need make jre, how compile new source .java files (after can compress rt.jar file).

thanks.

some of java sources make rt.jar generated during build process, scripts , other means. of properties files generated way, , of properties files turned java source contributes rt.jar. without doing complete build first , populating 'gensrc' directory, won't have sources make rt.jar.

taken from: http://www.java.net/forum/topic/jdk/java-se-snapshots-project-feedback/it-possible-just-build-rtjar

so when javac on java files inside src.zip won't compile dependency graph broken (missing generated files)

also have @ this: where full source code rt.jar?
