Matthew Hayes commented on DATAFU-132:
--------------------------------------
One potential issue I see with this is that it would be easy to accidentally
release a version of DataFu targeting Java 8, which then wouldn't work for
those folks who are using Java 7, which is the minimum version required for
Hadoop 2.7. This was the motivation behind the sweeney check. I'd feel a lot
more comfortable merging this change in if we had some protection against this.
One possible solution that comes to mind is using the {{release}} flag in
{{gradle.properties}} to control whether we validate the java version more
strictly or not. When we generate the source release we set this flag to true
so that SNAPSHOT is not appended to the artifacts. We can use the flag to do
this validation as well. Artifacts should be generated from the source release
only.
This will enable users to use Java 8 or other newer versions when developing
contributions but will help ensure we release artifacts that are still
compatible with Java 7.
Thoughts? I'll attach an updated patch shortly.
> Make DataFu compile with Java 8

> Key: DATAFU-132
> URL: https://issues.apache.org/jira/browse/DATAFU-132
> Project: DataFu
> Issue Type: Improvement
> Affects Versions: 1.4.1
> Reporter: Eyal Allweil
> Priority: Major
> Attachments: DATAFU-132.patch
>
>
> Currently DataFu only compiles with Java 7. It would be great if Java 8+
> could be used. The attached patch makes this possible by making the Java
> version check more permissive (anything above Java 7).
> I've done a build and tests, and deployed the resulting jar and tested a
> macro and UDF with it, compiling with Java 8.
