quickstart guide gradle build doesn't work

[vshwnth2]

Trying to follow https://github.com/linkedin/rest.li/wiki/Quickstart:-A-Tutorial-Introduction-to-Rest.li

On the first gradle build command inside /api folder, i get the following error:

Task :api:generateDataTemplate FAILED
[main] INFO com.linkedin.pegasus.generator.PegasusDataTemplateGenerator - Generating 1 files
Exception in thread "main" java.io.IOException: /Users/maheshvishwanath/sante-restli/api/src/mainGeneratedDataTemplate/java: non-existent directory

• What went wrong:
  Execution failed for task ':api:generateDataTemplate'.

Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1

If it helps, these are the versions I have installed locally:
gradle --version

should be the gradle version issue, if you use gradle 4.0, it will be fine, good luck!

[evanw555]

@vshwnth2 This is quite a delayed follow-up, but this was resolved, yeah?

[venkyvb]

The quick-start seems to be broken again. When I go the /api folder and do a gradle build I see the following error:

FAILURE: Build failed with an exception.

* Where:
Build file '/rest.li-master/examples/quickstart/build.gradle' line: 12

* What went wrong:
A problem occurred evaluating root project 'quickstart'.
> Cannot add task 'wrapper' as a task with that name already exists.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 436ms

When I change the following in the /rest.li-master/examples/quickstart/build.gradle

task wrapper(type: Wrapper) {
  gradleVersion = '4.6'
}

to

wrapper {
  gradleVersion = '4.6'
}

and then try gradle build in the /api folder I see the following error:

> Task :api:changedFilesReport FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':api:changedFilesReport'.
> You must declare outputs or use `TaskOutputs.upToDateWhen()` when using the incremental task API

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

any ideas as to what could be going wrong?

[evanw555]

@venkyvb Yeah, my guess is that this is something we forgot to clean up when upgrading to Gradle 5. See how we removed the wrapper task for the root build script in #242. I'm inferring that the guy who did the work didn't try building these sample projects (people often forget they're there). Could you try removing the wrapper task definition altogether? If it works, feel free to open a PR to fix this.

[liz2020]

@evanw555 I tried removing the wrapper task (line 12 - 14 in build.gradle) and it builds successfully. So, your suggestion works!

Task :api:generateDataTemplate FAILED

FAILURE: Build failed with an exception.

• What went wrong:
  Some problems were found with the configuration of task ':api:generateDataTemplate' (type 'GenerateDataTemplateTask').

  • In plugin 'pegasus' type 'com.linkedin.pegasus.gradle.tasks.GenerateDataTemplateTask' method 'generateFieldMask()' should not be annotated with: @input.

    Reason: Input/Output annotations are ignored if they are placed on something else than a getter.

    Possible solutions:

    1. Remove the annotations.
    2. Rename the method.

    Please refer to https://docs.gradle.org/7.4.2/userguide/validation_problems.html#ignored_annotations_on_method for more details about this problem.

  • In plugin 'pegasus' type 'com.linkedin.pegasus.gradle.tasks.GenerateDataTemplateTask' method 'generateLowercasePath()' should not be annotated with: @optional, @input.

    Possible solutions:

    1. Remove the annotations.
