Specifically regarding Java dependent packages, such as ant. Is it possible to install them via rpm, when using an alternate JVM/JDK? For example, If I install the Oracle JDK, can I use an ant package without installing OpenJDK? Is there anyway this can be done from an RPM?
I know I can specify which JDK to use, by executing
update-alternatives --config java. Additionally I'm specifying a JAVA_HOME, which works as expected. The only available choices seem to be, keeping 3 different JDK's installed, or installing everything manually.
