问题描述
我有以下libGDX项目: https://github.com/Glusk2 /sprouts
我尝试将checkstyle添加到根build.gradle文件中的整个项目，如下所示:
I've tried adding checkstyle to the entire project in the root build.gradle file, like so:
// ...
allprojects {
apply plugin: "eclipse"
apply plugin: "idea"
apply plugin: "checkstyle"
// ...
}
// ...
并将config/checkstyle/checkstyle.xml添加到根项目.
但是它不起作用.运行./gradlew build connectedCheck后出现此错误:
But it doesn't work. I get this error after running ./gradlew build connectedCheck:
:android:compileJava
<path-to-project>\sprouts\android\src\com\github\glusk2\sprouts\AndroidLauncher.java:3: error: package android.os does not exist

推荐答案
默认情况下，将checkstyle插件应用于Android gradle项目不会执行任何操作(不会添加任何checkstyle任务)，因为:
Applying the checkstyle plugin to an Android gradle project does nothing (it adds no checkstyle tasks) by default because:
Android Gradle插件； sourceSets {}
https://issuetracker.google.com/issues/36972352#comment21
但是在我的情况下，包含字符串"checkstyle"的任务列表如下所示:
But in my case, the task list containing the string "checkstyle" looked like this:
$ ./gradlew tasks --all | grep checkstyle
android:checkstyleMain - Run Checkstyle analysis for main classes //<-- this should not be here :)
core:checkstyleMain - Run Checkstyle analysis for main classes
desktop:checkstyleMain - Run Checkstyle analysis for main classes
html:checkstyleMain - Run Checkstyle analysis for main classes
ios:checkstyleMain - Run Checkstyle analysis for main classes
core:checkstyleTest - Run Checkstyle analysis for test classes
desktop:checkstyleTest - Run Checkstyle analysis for test classes
html:checkstyleTest - Run Checkstyle analysis for test classes
ios:checkstyleTest - Run Checkstyle analysis for test classes
该任务android:checkstyleMain为何添加到列表中?
How come that task android:checkstyleMain was added to the list?
事实证明这是原因(android项目build.gradle文件):
It turns out this was the reason (android project build.gradle file):
// ...
eclipse {
// ...
sourceSets {
main {
java.srcDirs "src", 'gen'
}
}
// ...
}
// ...
它设置了checkstyle插件可以检测到的sourceSets，但是配置显然不完整，因为任务android:checkstyleMain的构建失败.
上面的eclipse块添加了 Eclipse ADT 的配置插件，已经有一段时间不被支持了，所以我决定将其全部删除.
It set the sourceSets that the checkstyle plugin could detect, but configuration was obviously incomplete because the build failed for task: android:checkstyleMain.
The above eclipse block among others added configuration for the Eclipse ADT plugin, which has been unsupported for a while now so I've decided to remove that block altogether.
$ ./gradlew tasks --all | grep checkstyle
core:checkstyleMain - Run Checkstyle analysis for main classes
desktop:checkstyleMain - Run Checkstyle analysis for main classes
html:checkstyleMain - Run Checkstyle analysis for main classes
ios:checkstyleMain - Run Checkstyle analysis for main classes
core:checkstyleTest - Run Checkstyle analysis for test classes
desktop:checkstyleTest - Run Checkstyle analysis for test classes
html:checkstyleTest - Run Checkstyle analysis for test classes
ios:checkstyleTest - Run Checkstyle analysis for test classes
成功！但是我仍然没有设法使checkstyle与android项目一起工作.
Success! But I still haven't managed to get checkstyle working with the android project.
在阅读了有关checkstyle任务的许多类似问题后，这些问题并未显示在android项目中...
After reading many similar questions about checkstyle tasks not showing for android projects...
- Get Android gradle plugin & checkstyle working together / command line usage
- Checkstyle Plugin does not add gradle tasks
...我想出了解决方案.
... I've come up with the solution.
根build.gradle:
// ...
allprojects {
apply plugin: "eclipse"
apply plugin: "idea"
+ apply plugin: "checkstyle"
+ checkstyle {
+ configFile file("${project.rootDir}/config/checkstyle/checkstyle.xml")
+ }
// ...
}
// ...
Android build.gradle:
+task checkstyle(type: Checkstyle) {
+ source 'src'
+ include '**/*.java'
+ exclude '**/gen/**'
+ exclude '**/R.java'
+ exclude '**/BuildConfig.java'
+ classpath = files()
+}
+check.dependsOn "checkstyle"
// ...
-// sets up the Android Eclipse project, using the old Ant based build.
-eclipse {
- // need to specify Java source sets explicitly, SpringSource Gradle Eclipse -plugin
- // ignores any nodes added in classpath.file.withXml
- sourceSets {
- main {
- java.srcDirs "src", 'gen'
- }
- }
-
- jdt {
- sourceCompatibility = 1.6
- targetCompatibility = 1.6
- }
-
- classpath {
- plusConfigurations += [ project.configurations.compile ]
- containers 'com.android.ide.eclipse.adt.ANDROID_FRAMEWORK', 'com.android.ide.eclipse.adt.LIBRARIES'
- }
-
- project {
- name = appName + "-android"
- natures 'com.android.ide.eclipse.adt.AndroidNature'
- buildCommands.clear();
- buildCommand "com.android.ide.eclipse.adt.ResourceManagerBuilder"
- buildCommand "com.android.ide.eclipse.adt.PreCompilerBuilder"
- buildCommand "org.eclipse.jdt.core.javabuilder"
- buildCommand "com.android.ide.eclipse.adt.ApkBuilder"
- }
