请注意: 我创造了 this GitHub project to help you exactly produce the issue .

这里是Java 8和Gealle 4.6。如果您创建了一个新的Java分级项目 gradle init --type java-library 然后将Gradle CheckStyle插件配置为使用 Google's Checkstyle XML 它将立即失效:

plugins {
    id 'java-library'
}

apply plugin: 'checkstyle'

dependencies {
    testCompile(
        'junit:junit:4.12'
    )
}

repositories {
    jcenter()
    mavenCentral()
}

checkstyle {
    // Go to the Google Checks link above and paste its
    // contents into checkstyle.xml
    config = rootProject.resources.text.fromFile('buildConfig/checkstyle/checkstyle.xml')
}

用这个配置,运行 ./gradle clean build 生产:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':checkstyleMain'.
> Unable to create a Checker: configLocation {/Users/myuser/workspace/test-gradle-checkstyle/buildConfig/checkstyle/checkstyle.xml}, classpath {/Users/myuser/workspace/test-gradle-checkstyle/build/classes/java/main:/Users/myuser/workspace/test-gradle-checkstyle/build/resources/main}.

* 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

$ pwd

我想知道为什么?!

编辑(对于未来的谷歌用户):

使用 --stacktrace ,实际误差为

cannot initialize module TreeWalker - Token "METHOD_REF" was not found in Acceptable tokens list in check com.puppycrawl.tools.checkstyle.checks.whitespace.SeparatorWrapCheck
