-------------------------------------
Summary: Fix Java version detection in common-build.xml, use
correct source version for javadocs, fail build on unsupported java version
when documentation linting is enabled
Key: LUCENE-4763
URL: https://issues.apache.org/jira/browse/LUCENE-4763
Project: Lucene - Core
Issue Type: Bug
Components: general/build
Affects Versions: 4.1
Reporter: Uwe Schindler
Assignee: Uwe Schindler
Fix For: 4.2, 5.0
Followup after the discussion on mailing list; this issue tries to fix the
following problems in the ANT build:
- ${ant.java.version} is incorrect for Java 8 with ANT < 1.8.3 (it says its
Java 7, so we habve otherwise no chance to detect java 8). This can be fixed by
the same set of reflection tests from Constants.java. We can also fail build
early if somebody uses Java 1.5
- javadoc macro uses this incorrect ant.java.version property to execute
javadocs. The source attribute of the javac task must be ${javac.source} (like
javac)
- If we run builds by Jenkins, we silently disable targets that cannot be
executed. This has effects on real developers. If a real person executes the
ant tasks it should not pass silently, it should tell the user that his
configuration is unsupported. This can be done by passing a hidden
"jenkins-build" property down.
