Stefan Seifert commented on SLING-7644:
---------------------------------------
ah, the reason is this commit:
https://github.com/apache/sling-maven-sling-plugin/commit/9579510a3c3efde58319fc25749836c18c4e9644
which references
http://repo1.maven.org/maven2/org/apache/geronimo/specs/geronimo-json_1.1_spec/1.0/geronimo-json_1.1_spec-1.0.pom
http://repo1.maven.org/maven2/org/apache/geronimo/genesis/genesis-java8-flava/2.3/genesis-java8-flava-2.3.pom
which compiles to java 8. strange why this spec requires java 8. we may
downgrade to json spec 1.0, i assume the code has no direct dependencies to the
API updates.
on the other hand: what speaks against just declaring the java 8 dependency for
the maven-sling-plugin - who wants to run it with java 7? it's only required in
the development environment.
