I'm trying to create an rpm package with a dependency on java 11; however, it seems like the openjdk and Oracle java 11 packages don't provide any overlapping java virtual packages.

OpenJDK Java 11 provides:

$ repoquery --provides java-11-openjdk
java-11 = 1:
java-11-openjdk = 1:
java-11-openjdk(x86-32) = 1:
jre-11 = 1:
jre-11-openjdk = 1:
java-11 = 1:
java-11-openjdk = 1:
java-11-openjdk(x86-64) = 1:
jre-11 = 1:
jre-11-openjdk = 1:

The Oracle Java 11 installer provides:

$ rpm -qp --provides /tmp/jdk-11.0.2_linux-x64_bin.rpm 
jdk-11.0.2 = 2000:11.0.2-ga
jdk-11.0.2(x86-64) = 2000:11.0.2-ga

How do I set my packages' dependencies to be flexible enough to work with either java11?

I thought rpm boolean dependencies might help, but I could find no information about updating rpm to version 4.13. If I set my packages dependencies to: Requires: jre-11 >= 11, rpm >= 4.13 installation fails with:

Error: Package: MYPACKAGE
           Requires: rpm >= 4.13
           Installed: rpm-4.11.3-32.el7.x86_64 (installed)
               rpm = 4.11.3-32.el7
           Available: rpm-4.11.3-35.el7.x86_64 (base)
               rpm = 4.11.3-35.el7

Version 4.13 of rpm just doesn't seem to be available? I'm using CentOS7, but the same happens on RHEL 7.5 too.


So, as you pointed out, the best would be if both packages could be made to have a common "Provides".

Since this is probably not within your reach, another option is to create a pseudo RPM as a proxy for the Oracle Java 11 RPM.

  • Name: java-11-oracle (for example)
  • Provides: java-11 or any other relevant value from the openjdk RPM
  • Requires: java >= 11 (or jdk, or jre...)
  • %files: empty section (you can omit it)

In your own package, add a dependency to the Provides: that is now in common between that proxy RPM and the openjdk one.

Your package would then be installable in one the following situations:

  • OpenJDK 11 is installed or available in the repositories
  • Oracle's Java 11 RPM and your java-11-oracle RPM are installed or available in active repositories.
