Hi,
I've tried to checkout Jenkins CI source code and generate an Eclipse project
for it (see instructions in [1]). Unfortunately generated Eclipse projects
seemed to contain errors, which I first reported as a Jenkins bug [2]. Further
investigation revealed that even though Jenkins is build with "javac -source
1.5 -target 1.5" parameters, they use javac from JDK6u18 or later and rely on
animal-sniffer plug-in to ensure that their code is java5-compliant.
Unfortunately, it seems that neither Sun's javac nor Animal Sniffer noticed the
presence of @Override annotations on methods implementing interfaces, which is
not allowed in Java 5 and is ok in Java 6 [3]. On the other hand, Eclipse Java
Compiler does notice them and mark each one as error.
Long story short, I tried to modify eclipse project generation so that in the
.settings/org.eclipse.jdt.core.prefs instead of this:
org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.5
eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.source=1.5
org.eclipse.jdt.core.compiler.compliance=1.5
I get this (look at the compliance):
org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.5
eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.source=1.5
org.eclipse.jdt.core.compiler.compliance=1.6
but didn't find a way to configure maven-eclipse-plugin.
Has anybody else experienced this problem? Can you suggest any ideas?
