gradle-scalastyle-plugin's Introduction

Scala Style Gradle Plugin

Instructions

maven repo: http://jcenter.bintray.com/
groupId: org.github.ngbinh.scalastyle
artifactId:  gradle-scalastyle-plugin_2.11
version: 1.0.1

Use artifactId: gradle-scalastyle-plugin_2.10 if you want to use with Scala 2.10

  apply plugin: 'scalaStyle'

Add following dependencies to your buildScript

  classpath "org.github.ngbinh.scalastyle:gradle-scalastyle-plugin_2.11:1.0.1"

Configure the plugin

  scalaStyle {
    configLocation = "/path/to/scalaStyle.xml"
    includeTestSourceDirectory = true
    source = "src/main/scala"
    testSource = "src/test/scala"
  }

Other optional properties are

  outputFile  //Default => $buildDir/scala_style_result.xml
  outputEncoding //Default => UTF-8
  failOnViolation //Default => true
  failOnWarning //Default => false
  skip  //Default => false
  verbose //Default => false
  quiet //Default => false
  includeTestSourceDirectory //Default => false
  testConfigLocation //Separate configuration file to be used for test sources
  inputEncoding //Default => UTF-8

Full Buildscript Example

  apply plugin: 'scalaStyle'

  buildscript {
    repositories {
      jcenter() // only work after gradle 1.7
    }

    dependencies {
      classpath 'org.github.ngbinh.scalastyle:gradle-scalastyle-plugin_2.11:1.0.1'

gradle-scalastyle-plugin's Issues

Bug + fix in multimodules

gradle-scalastyle-plugin/gradle-scalastyle-plugin_2.11/src/main/groovy/org/github/ngbinh/scalastyle/ScalaStyleTask.groovy

Line 77 in 0cea2e2

XmlOutput.save(config, outputFile, outputEncoding, messages)

You should change outputFile to project.file(outputFile)

Symptoms: empty xml file in submodule, actual xml file in root module or where CWD is

Publish Plugin to alternative repo now that Bintray/Jcenter is EOL

ScalaStyle Now 1.0

Is there a plan to upgrade the plugin to use the latest Scalastyle? Or better yet, is there a way to configure the version the plugin will use?

Thanks.

Discover sourceSets automatically that have scala sources and create dynamic tasks for them

Hello,

It's a great plugin, but I really miss some of the functionality.
For example I have not only main/scala and test/scala but also integrationTest/scala and gatling/scala and I can't just run scalastyle on all of them.

Maybe we could improve the plugin so that it will create scalastyleMain, scalastyleTest, scalastyleIntegrationTest, scalastyleGatling automatically and the parent task scalastyle to run them all?

We could make an extension scalastyle using named domain object container e.g.

scalaStyle {
  // global config (use in case there is no override for specific source set)
  config = file("$rootDir/scalastyle.xml")
  // globally configure to fail on warnings
  failOnWarnings = true  
  
  // not sure it's the right name, or 
  // maybe even we don't need this nesting and should just handle a missing method call
  sourceSets {
    // gatling is supposed to be a DSL, 
    // so I don't really want production code checks to be run on it, 
    // but rather some basic checks and DSL specific
    gatling {
      config = file("$rootDir/scalastyle-test.xml")
    }
  
    test {
      // do not fail on warnings when checking test source set
      failOnWarnings = false  
    }

    garbage {
      // do not even create a task for this source set
      skip = true
    }
  }
}

Usage:

// runs main source set checks
gradlew scalaStyleMain
// error, no task for garbage source set
gradlew scalaStyleGarbage
// runs all (scalaStyleMain, scalaStyleTest)
gradlew scalaStyle

If somebody else is interested, I can work on that.
I have something similar like I proposed implemented as a plugin in buildSrc, however I made it as a JavaExec task (just running a scalastyle jar with needed arguments)

Log spam

If I run scalastyle with quiet true specific errors do not get reported. If I run scalastyle with quiet false specific errors do get reported but the log is spammed with Found 0 warnings and Found 0 errors.

I think a third option would be nice or maybe just not log the Found 0 ... lines.

0.8.1 does not generate violations

I upgraded from 0.7.2 to 0.8.1 and can't make a violation error occur.

I simplified my project down to a configuration with only 1 check, and a file that should fail, and still no failure.

Code cleanup/refactor

One round of clean up might be needed.

Should only run when there are changes

The scalastyle plugin does not support incremental building. It should only run when there are changes since the last run.

cannot find the plugin version 1.0.0 in jcenter

forget to publish?:sweat_smile:

Any reason for no build available for Scala 2.12 ?

I was going through https://mvnrepository.com/artifact/org.github.ngbinh.scalastyle/gradle-scalastyle-plugin and did not find any plugin which was published for 2.12. Is there any particular reason for that?

Allow loading XML cfg file ftom classpath

The maven scalastyle plugin allows for loading in style .xml files through the classpath, it would be a good aide to migration if the gradle plugin likewise allowed the file to be loaded from classpath

testSource property should allow a fileTree instead of a String

Gradle allows you to specify multiple working sourceSets. It will be ideal if we can take advantage of this functionality for checking scalaStyle in more than one sourceSet.

Support gradle build cache

When a particular module doesn't have any modified source code, there is no need to run scalastyle on that module. Gradle already have build cache for this. Could this plugin leverage on that cache? It will greatly reduce our total build time.

Run the analysis on files specified in the CLI

I wish to run something like that
gradle scalaStyle --only-include aa/bb/cc.scala dd/ee/gg.scala kk/hh/vv
The idea is to create a pre commit hook that run the analysis on the file modified and created on that particular commit.

gradle-scalastyle-plugin_2.12 not showing up in jcenter

I can see it here: https://bintray.com/ngbinh/maven/gradle-scalastyle-plugin_2.12
But it doesn't show up where gradle itself will look for it: https://jcenter.bintray.com/org/github/ngbinh/scalastyle/

0.8.1 is not published

https://jcenter.bintray.com/org/github/ngbinh/scalastyle/gradle-scalastyle-plugin_2.11/

Support scala 2.12

Please add scala 2.12 support with the next release.

Support for scala 2.10

The scalastyle website claims that 0.6.0 supports both scala 2.10.x and 2.11.x. On casual inspection, it looks like the Gradle plugin only supports 2.11.x -- is that true? I'd be happy to contribute 2.10 support if you can give me some general pointers.

(I need 2.10 support because I'm working with Apache Spark, which is going to be on 2.10 for the near future.)

Publish 2.12 artifact

I couldn't find the Scala 2.12 artifact published anywhere, any plans to publish it soon?

configuration file from URL

Add support to read configuration file from URL

Add a license

Currently we cannot use this within our enterprise because there is no license specified - please consider adding a specific open source license to clarify the terms of reuse

Do not check test source set with configuration for main when testConfigLocation is defined

When I use the following configuration:

scalaStyle {
    configLocation = "scalastyle-config_main.xml"
    testConfigLocation = "scalastyle-config_test.xml"
    includeTestSourceDirectory = true
    source = "src/main/scala"
    testSource = "src/test/scala"
}

, the test source set is checked twice with configLocation and testConfigLocation configurations, resulting in unnecessary warnings for test source set since the rules for test source set are less strict in my case.
If I set includeTestSourceDirectory to false, code is checked as expected, the main source set with configLocation config and the test source set with testConfigLocation config.

I suggest that:

either documentation should say that includeTestSourceDirectory = true uses configLocation configuration;
or fix the plugin so includeTestSourceDirectory = true uses testConfigLocation if defined, configLocation otherwise.

latest version failed on scala 2.12 features

if I have in code val l = List(1, 2, 3, ) it will fail on compilatioin error even it is OK on Scala 2.12

Other checks than org.scalastyle.* on scalastyle-config.xml

I've got some custom checks implemented I was using in maven with a success, e.g.:

 <check customId="nonascii" level="error" class="com.my.group.NonASCIICharacterChecker" enabled="true"/>

It does not work with gradle-scalastyle-plugin.
How I can tell the gradle-scalastyle plugin where to find those dependancies for such a custom checker?

Another thing is, that there is no error printed, that couldn't find it. For example: if I add an obviously bad rule like this:

  <check customId="blabla" level="error" class="ClassThatDoNotExistForSureSoItShouldFail" enabled="true"/>

It just runs without any error. I wish I know that there is something wrong with the config.

Make this repository not a fork

Since it looks like this is the new home of the plugin, it would be better not to have it as a fork. You may need to delete it and recreate as an independent repository, then push all the commits to it.

This will be clearer and also have the advantage that the repository will be indexed by github for searching etc, which currently, as a fork, it is not.

Publish on Gradle Plugins

Publish gradle-scalastyle-plugin on https://plugins.gradle.org/ , so that it's easier for newbies to install.

Add support for multiple source and testSource locations

Compile with JDK7

The plugin currently is compiled using JDK8, I'm assuming this is not required though. Can you recompile with 1.7 compat?

Gradle pre-defaulting 2.8 library when running scalastyle-plugin

Given the sample build.gradle buildscript entries, the script is failing when running scalaStyle because it is at some point unable to load Scala.predef..colon less colon..

Classloader logs show that gradle is loading scala library 2.8 which is in the gradle init.d directory

Have you seen this issue before and do you have suggestions on how to make this work for the 2.11 build of this plugin?

Implement tests and CI

sample hello world

I tried it with hello world (scala 2.11.7, jdk 1.8.45, gradle 2.7, gradle-scalastyle-plugin_2.11:0.8.0) and was unable to run 'gradle scalaStyle'
output is:
gradle clean scalaStyle
:clean UP-TO-DATE
:scalaStyle FAILED
FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':scalaStyle'.

java.lang.Exception: Scala check error
BUILD FAILED

Can someone upload a helloworld that works?
From the stack trace it looks like it has trouble to read the xml (I used the extracted the default_config.xml from scalastyle_2.11-0.7.0.jar)
Thanks
-cl

--stacktrace shows:

update:
tried older version - gradle-scalastyle-plugin_2.11-0.7.2.jar and it worked
however I need org.scalastyle:scalastyle_2.11:0.7.0 which is only supported by gradle-scalastyle-plugin_2.11:0.8.0

can someone help?
