That's good news. Will they always be at the same path? If not (or even if so) would it be possible to define properties in Maven host-global settings.xml that point to the home directories? Commons Parent uses the convention that JAVA_1_5_HOME points to the home directory of Java 1.5 similarly for other Java versions. These are then used in profiles - e.g. java-1.5 - which override the java compiler and runtime for compilation and testing. The variables are also excluded from OSGI builds. To avoid cluttering the name-space, the variable is only defined if the profile is selected. For example: <profile> <id>java-1.5</id> <properties> <JAVA_1_5_HOME>${env.JAVA150_HOME}</JAVA_1_5_HOME> </properties> </profile> <profile> <id>java-1.6</id> <properties> <JAVA_1_6_HOME>${env.JAVA160_HOME}</JAVA_1_6_HOME> </properties> </profile> The above assumes that the relevant environment variables have been set, however that is not necessary; the paths can be listed directly, for example: <JAVA_1_5_HOME>/home/jenkins/tools/java/latest1.5</JAVA_1_5_HOME> Would this be possible? > A. > > On Thu, Jan 8, 2015 at 3:20 AM, sebb <seb...@gmail.com> wrote: > >> On 8 January 2015 at 11:09, Andreas Lehmkühler <andr...@lehmi.de> wrote: >> > Hi, >> > >> >> sebb <seb...@gmail.com> hat am 8.
