Bug 1392131

This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.

Updating closure-compiler would be beneficial for DomTerm (see issue 1424890). It would reduce the JavScript by about 100k (before zip-compression).

The version of closure-compiler in f26 is very old!

There are many new releases with important features.

Once such feature is the processing of UMD modules which landed in 2016-06-19 [0]. Without this feature, processing the majority of libraries in npm with closure compiler is not possible.

I checked out the source for this package, and there have been some changes:

1. the 'maven-release-vXXXX.tar.gz' is now called 'closure-compiler-parent-vXXXX.tar.gz'

2. Three new mvn dependencies which are not packaged by fedora: com.google.errorprone:error_prone_annotations, com.google.auto.value:auto-value, com.google.jsinterop:jsinterop-annotations)

That's as far as I got. I'm afraid I don't have time this weekened to dive down that rabbit hole up maven deps.

This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

This doesn't just apply to Fedora 26.  The 20160315 Closure Compiler version is still being used in Fedora 27, 28, and 29 (https://apps.fedoraproject.org/packages/closure-compiler/builds/).  The current latest version is 20180610.

The situation is not good. There's a bunch of new dependencies. Apart from  com.google.jsinterop:*,
google's truth, error-prone, checker-framework, and some other stuff. Following the dep tree we
immediately run into projects using gradle to build, and gradle requires groovy and kotlin. I could
package a few maven projects, but anything that requires gradle is a no-go currently.
(If anyone wants to follow up on that, I can post the specs for error-prone and truth, which
don't build because of missing deps).

I also looked into converting gradle.build files into maven using gradle2maven, but g2m only supports
some very basic constructs, so this doesn't go anywhere.

Dunno, without a major effort to support gradle in Fedora, I think it'll be harder and harder to
build java projects in Fedora.

I'll push a fix for FTBFS in F32+, but with the same old version.

This package has changed maintainer in the Fedora.
Reassigning to the new maintainer of this component.

Automation has figured out the package is retired in rawhide.
