Virtual package 'overlay' for Oracle JDK

The official JDK package does not provide 'java' ( Provides: java ).

This repository provides 2 packages:

1. virtual-java that ( Provides: java ) + requires 'jdk' in order to work around this bug - nothing else.
2. neutral-java that only ( Provides: java )

The official package does install /usr/bin/java (as a symlink), but does not add an alternative which means it cannot properly coexist with other installations. This is also remedied here.

In order to build this package you need make and rpmdevtools (rpmbuild):

yum install -y make rpmdevtools

git clone https://github.com/keystep/virtual-java-rpm.git && \
cd virtual-java-rpm 

./build

./build PACKAGE=neutral-java

This should produce an RPM that can be found in dist/

Example:

virtual-java-1.7-1.noarch.rpm

you can override VERSION and RELEASE too. Example:

./build PACKAGE=neutral-java VERSION=1.8.0 RELEASE=11

Add this package to your local repo. Your applications (in my case tomcat) can now depend on 'java' and be satisfied with the (already) installed jdk without forcing an install of the default openjdk.

• Should this package be called virtual-jdk rather than virtual-java?
• Add a fix for update-alternatives ?
