</suppressions>

checkstyle {
    toolVersion '6.11.1'
    showViolations true
}
check.dependsOn 'checkstyle'

task checkstyle(type: Checkstyle) {
    configFile file("${project.projectDir}/config/quality/checkstyle.xml")
    // Where my checkstyle config is...
    configProperties.checkstyleSuppressionsPath = file("${project.projectDirr}/config/quality/suppressions.xml").absolutePath // Where is my suppressions file for checkstyle is...
    source 'src'
    include '**/*.java'
    exclude '**/gen/**'
    exclude "**/test/**"
    classpath = files()
}

狠一点可以在build.gradle里加上下面这个，每次构建都会检查

project.afterEvaluate {
    preBuild.dependsOn 'checkstyle'
}

<!--
    Checkstyle configuration that checks the Google coding conventions from Google Java Style
    that can be found at https://google.github.io/styleguide/javaguide.html.
    Checkstyle is very configurable. Be sure to read the documentation at
    http://checkstyle.sf.net (or in your downloaded distribution).
    To completely disable a check, just comment it out or delete it from the file.
