I can build using the java 7 compiler no problem, but is it possible to output
java 7 as well?
There are three places in the parent pom that I can see where the java version
comes into play. (pasted below)
I tried building with:
mvn clean install -Dsling.java.version=7 -e
And I get the exception that's shown in the maven-antrun-plugin in the pom.
Building with:
mvn clean install -Dsling.java.version=6 -e
works fine.
I can live with Java 6, but it's EOL'd by Oracle at this point. And when I
build one of my own bundles with java 7 as the target and install it into sling
built to another java version (I'm not sure if it was 5 or 6), I get errors
that look like byte code incompatibility problems.
