Tasks created when not used

[slowr]

Running gradle help for a big project, nebula.lint plugin creates 3 tasks per project even though we don't use them (generateGradleLintReport, compileJava, compileTestJava, etc). This has an impact on configuration time when you run gradle.

For more information take a look on gradle's task configuration avoidance documentation.

For example for me it creates 1082 tasks when running gradle help:

I can look into this and create a PR that will register these tasks and not create them if it is not necessary.

Hi @slowr ,

Thanks for bringing this to our attention. We will take a look on the lint side of things. We configure some task to always run so we would like registering in some cases only.

With that said, the fact that you have compileJava, compileTestJava should be on your project or other plugin. Lint does not register does tasks.

Take this multi module setup as example: https://github.com/rpalcolea/lint-multiproject-sample

other-thing module does not apply java plugin. If you look at the tasks, you won't see compileJava at all

❯ ./gradlew :other-thing:tasks --all

> Task :other-thing:tasks

I'd suggest to look at your build and see if you don't apply java plugin to all subprojects by default. In that case, I believe gradle creates the tasks always

V16.0.0 contains https://github.com/nebula-plugins/gradle-lint-plugin/pull/265

[slowr]

The build scan says in detail which tasks are created from which plugin and nebula.lint is the one to blame. If you call functions like getByName or getByPath this creates the task and the correct way is to use TaskProvider<Task>'s named function instead.

root project:

sub-project:

[rpalcolea]

16.0.1 has a change for that https://github.com/nebula-plugins/gradle-lint-plugin/pull/267

You should be good now

[slowr]

@rpalcolea seems that you missed one thing :D

in GradleLintPluginTaskConfigurer.java:52

project.tasks.withType(AbstractCompile) { abstractCompileTask ->

should be

project.tasks.withType(AbstractCompile).configureEach { abstractCompileTask ->

and then the tasks are only 1 which is the autoLint! Thanks a lot for the fast responds.

[rpalcolea]

ha! good catch, pushing out 16.0.2. Should be out soon!

Seeing some

 > Could not create task ':compileJava'.
    |         > DefaultTaskContainer#NamedDomainObjectProvider.configure(Action) on task set cannot be executed in the current context.
    |       

with the change https://github.com/nebula-plugins/gradle-lint-plugin/pull/268 will take a look at it on Monday

[rpalcolea]

alright v16.0.2 is out now with the change @slowr https://github.com/nebula-plugins/gradle-lint-plugin/pull/268

can you give it a whirl?

[slowr]

Yes now it works correctly and only creates the autolint task! :tada: Thanks a lot for the fast solution :)
