hi, i'm try to build a java package for epel-6 which use java-8. unfortunately it seem it's not enough to simple add BuildRequires: java-1.8.0-openjdk-devel since it's install it, but also still install during the mock setup session old java packages ie: java-1.5.0-gcj x86_64 1.5.0.0-29.1.el6 os 137 k java-1.6.0-sun x86_64 1:1.6.0.45-1jpp.1.el6 os 25 M java-1.7.0-ibm x86_64 1:1.7.0.5.0-1jpp.2.el6_4 os 73 M java-1.7.0-ibm-devel x86_64 1:1.7.0.5.0-1jpp.2.el6_4 os 7.5 M java-1.7.0-oracle x86_64 1:1.7.0.45-1jpp.2.el6_4 os 28 M and i'm not bale to exclude them. in rpm the is a Obsoletes: but there is no such thing as "BuildRequiresObsoletes":-( what's more i can't run system-switch-java since it's required root access and there is no command line option to switch to a given specific java version. so during build the system use the default javac which is not java8 but ibm's java7 (IBM J9 VM (build 2.6, JRE 1.7.0). is there any way to force java8? or is there any way to exclude other java vm jre to install into mock during build? thanks in advance. regards. -- Levente "Si vis pacem para bellum!" -- java-devel mailing list java-devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/java-devel
