Hello,

Our pde headless build has been supporting java 1.6 as minimum requirement. We got a request to change it and support Java 1.5.

To do so, I did these steps:

Changed the MANIFEST.MF for my 2 plugins to:
Bundle-RequiredExecutionEnvironment: JavaSE-1.5

Then in my product I changed the launcher from:
<vm>
<windows include="true">org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6
</windows>
</vm>

to

<vm>
<windows include="true">org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5
</windows>
</vm>

Am I missing a step?

When I try to build I get this error and the build fails:

[java] [eclipse.generateFeature] Missing Constraint: Bundle-RequiredExecutionEnvironment: JavaSE-1.5

Thank you.

Are you supplying multiple JREs to your PDE build? My build.properties includes entries like:

JAVA60_HOME=/opt/public/common/jdk-1.6.0_10
JAVA50_HOME=/opt/public/common/jdk-1.5.0_16
...
JavaSE-1.6=${JAVA60_HOME}/jre/lib/resources.jar:${JAVA60_HOME}/jre/lib/rt.jar:${JAVA60_HOME}/jre/lib/jsse.jar:${JAVA60_HOME}/jre/lib/jce.jar:${JAVA60_HOME}/jre/lib/charsets.jar
J2SE-1.5=${JAVA50_HOME}/jre/lib/rt.jar:${JAVA50_HOME}/jre/lib/jsse.jar:${JAVA50_HOME}/jre/lib/jce.jar:${JAVA50_HOME}/jre/lib/charsets.jar

Hello Paul, thank you so much for your reply.

No I do not have these entries in my build.properties. I will add them and try again. How would you explain the fact that this runs for 1.6 without them though?

Thanks!

I'm not sure why 1.6 only worked. What JRE were you using to run your headless builds?

I do know that our stuff doesn't work without all of the BREEs defined in our build.properties.

But looking back on your original post, shouldn't it be:

Bundle-RequiredExecutionEnvironment: J2SE-1.5

JavaSE-1.5 doesn't exist.

Maybe you require a bundle that still wants 1.6?
