test: adding java 7 check #1847

suztomo · 2023-05-08T19:51:15Z

We haven't run the Java 7 builds for a while even though the README.md says Java 7 target. Let's clarify the current situation by installing the check again.

It turned out that the google-http-client-jackson2 and google-http-client-appengine modules require Java 8 or higher due to their dependencies. We keep the compilation target for Java 7 so that the users can tweak some old version of the dependencies.

The surefire (unit test) plugin's "jvm" option is the core of this Java 7 check. Guava's warning about Java 7 tells that the test is indeed running on Java 7:

https://github.com/googleapis/google-http-java-client/actions/runs/4927699269/jobs/8805047743?pr=1847

Fixes #1713
Closes #1721

suztomo · 2023-05-08T20:25:53Z

It turned out that Maven wrapper does not work with Java 7.

Guava's warning about Java 7 tells that the test is indeed running on Java 7:

+      with:

I believe this is the last version of maven that supports Java 7, right? I don't think anyone is going to manually update this, but would it helpful to add a blurb as to why this set to 3.8.8 ?

Actually this Maven does not need to work for Java 7. In fact this check does not run Maven via Java 7. (Maven calls Java 7 when running surefire unit tests)
