[GitHub] [netbeans] sdedic opened a new pull request #1578: NETBEANS-3250:
Fix warnings from annotation processors.
sdedic opened a new pull request #1578: NETBEANS-3250: Fix warnings from annotation processors.
URL: https://github.com/apache/netbeans/pull/1578
See [NETBEANS-3250](https://issues.apache.org/jira/browse/NETBEANS-3250).
Most of annotation processors are not affected by features added to Java, and once they declare a specific `@SupportedSourceVersion`, they start to produce warnings during compilation with the next released JDK:
```
"warning: Supported source version 'RELEASE_7' from annotation processor 'org.netbeans.modules.openide.util.ServiceProviderProcessor' less than -source '1.8'"
```
So usually it's best to declare the processor to support `SourceVersion.latest()`, but that cannot be done using annotation. Most of annotation processors in NetBeans generate layers, and derive from `LayerGeneratingProcessor`, so I've decided to change that base class.
I've split the work into several commits, to make it cleaner for review:
* b2acf687 - changes to `org.openide.util.lookup` and `org.openide.filesystems` to the abstract processor impl, increased specification version
* 5d32a993 - adapted the rest of Util + Filesystems processors.
* 467f689b - updated the rest of the GIT repository
* 3126f706 - hint that looks for obsolete or missing `@SupportedSourceVersion`, and suggest solutions
* daf35838 - code generation support in Editor (hooked onto ALT-INSERT) that generates override of `getSupportedSourceVersion` + some fixes to the shared code.
