This PR makes it possible to build the Nomulus code base using Java 17.
Building with Java 11 continue to be possible and the resulting bytecodes are
still at Java 8 level. Also upgraded Gradle to 8.5.
There are several necessary changes to make this happen:
1. Some Gradle plugins need to be upgraded to support Java 17, notably
errorprone. As a result, a lot more "errors" were caught and corrected.
2. All test code are now built and run at Java 8 level. Previously it was left
undefined (which defaults to the version of the compiler) and had led to
situations where we inadvertently called Java 8+ features in production that
are not caught by tests. The change also made the java8compatibility subproject
obsolete, which is therefore removed.
3. Removed the docs subproject. Its main use is to generate flows.md, but it
relies heavily on Java internal APIs that have changed significant with each
version. Upgrading to Java 11 required extensive refactoring of the code there,
and Java 17 again removed many APIs that were used. I don't think it is worth
the maintenance effort just to have a tool to generate flows.md which no one
actually reads.
4. Capped a few GCP dependencies because the latest version depends on
grpc-java >= 1.59.0, which includes a runtime incompatibility
(https://github.com/grpc/grpc-java/releases/tag/v1.59.0).
This includes removing (hopefully temporarily) the gradle-lint plugin as
it is incompatible with various Gradle versions (see
https://github.com/nebula-plugins/gradle-lint-plugin/issues/393). This
is somewhat unfortunate since the plugin is useful for removing unused
dependencies, though with the relatively small amount of Gradle code we
write hopefully it will not be missed much. If Nebula changes their
code to be compatible with Gradle 8+, we can re-add it easily.
This upgrade means we can remove the code added in 342051e1.
This is an 'easy' upgrade that requires a minor change in
common/build.gradle and the removal of an unnecessary import in buildSrc.
Gradle 7.4 and above has breaking changes that break the latest nebula lint plugin. We may have to wait a while.
* Update GCL dependency to avoid security alert
This required a few changes in addition to the dependency update.
- a few transitive / required dependency updates as well
- updating soyutils_usegoog.js and adding checks.js because they're
necessary as part of the Soy compilation process
- Using a trustedResourceUri in the buildSrc Soy compilation instead of
a string
- changing the arguments to the Soy-to-Java compiler to comply with the
new version
- Moving all Soy UI files to be in the registrar directory. This was
not the case before due to previous thinking that we'd have separate
admin and registrar consoles -- this is no longer the case so it's no
longer necessary. This necessitated various refactorings and reference
changes.
- The new soy-to-javascript compiler requires this, as it removes the
"deps" param that we were previously using to say "use the general UI
utils as dependencies for the registrar-console files".
- Creating a SQL environment and loading test data in the test server
main method -- previously, the local test server did not work.
- Fix some JS code that was referencing now-deleted library functions
- Removal of the Karma tests, as the karma-closure library hasn't been
updated since 2018 and it no longer works. We never noticed any errors
from the Karma tests, we never change the JS, and we have the
Java+Selenium screenshot differ tests to test the UI anyway.
* Fix some low-hanging code quality issue fruits
These include problems such as: use of raw types, unnecessary throw clauses,
unused variables, and more.
* Update a few plugins for Java 11 compatibility
Guice 5.0.1 is now compatible with Java 11. However we don't
directly depend on Guice. Rather Soy depends on Guice. So I added a
direct dependency on Guice 5.0 just before Soy in order to frontload Soy
and pull in the newer version.
Mockito 3.7.7 is now compatible with Java 11. The complication is that
we need to use the inline version of Mockito, which among other things
also allows mocking for final classes (hooray!). It will eventually
become the default Mockito mock maker but for now it needs to be
manually activated.
Note that the inline version now introduces another warning:
```
OpenJDK 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended
```
Which I think is WAI due to how the inline mock maker works. Waiting on
the author to confirm.
After these to changes the only illegal reflective access is caused by
App Engine SDK tools, which we will rid ourselves of when we migrate off
of GAE.
* Restore package-lock.json
* Get rid of all remaining JUnit 4 usages except in prober & proxy subprojects
Caveat: Test suites aren't yet implemented in JUnit 5 so we still use the ones
from JUnit 5 in the core subproject.
* Fix some build errors
This adds an entriesToImmutableMap() collector that can be used in place of
toImmutableMap(Map.Entry::getkey, Map.Entry::getValue()).
It also fixes up some existing calls that use toImmutableMap() when terser
alternatives exist.
