Question

我们有一个运行Checkstyle的Gradle脚本：

apply plugin: 'checkstyle'

checkstyle {
    configFile rootProject.file('config/strict_checkstyle.xml')
    ignoreFailures false
    showViolations true
    toolVersion = rootProject.ext.checkstyleVersion
}

task Checkstyle(type: Checkstyle) {
    configFile rootProject.file('config/strict_checkstyle.xml')
    source 'src'
    ignoreFailures false
    showViolations true
    include '**/*.java'
    classpath = files()
}

// adds checkstyle task to existing check task
afterEvaluate {
    if (project.tasks.getByName("check")) {
        check.dependsOn('checkstyle')
    }
}

与此strict_checkstyle.xml文件一起

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<!DOCTYPE module PUBLIC
        "-//Puppy Crawl//DTD Check Configuration 1.2//EN"
        "http://www.puppycrawl.com/dtds/configuration_1_2.dtd">

<module name="Checker">

    <module name="FileLength"/>
    <module name="FileTabCharacter"/>

    <module name="TreeWalker">

        <module name="SuppressionXpathFilter">
            <property name="file" value="config/app_checkstyle_suppressions.xml"/>
            <property name="optional" value="false"/>
        </module>

        <module name="SuppressionXpathFilter">
            <property name="file" value="config/api_checkstyle_suppressions.xml"/>
            <property name="optional" value="false"/>
        </module>


        <!-- Checks for imports -->
        <!-- See http://checkstyle.sf.net/config_import.html -->
        <module name="AvoidStarImport"/>
        <module name="IllegalImport"/>
        <module name="RedundantImport"/>
        <module name="UnusedImports"/>

        ...

如您所见，我们为两个gradle模块app和api设置了抑制基线。这适用于我们的CI机器和除一个之外的所有开发机器。他遇到此错误：

What went wrong:
Execution failed for task ':module:Checkstyle'.
> Unable to create Root Module: config {/Users/user/our_application/config/strict_checkstyle.xml}, classpath {null}.
* 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.

使用--stacktrace运行会显示问题：

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':component:Checkstyle'.
...
Caused by: : Unable to create Root Module: config {/Users/user/our_application/config/strict_checkstyle.xml}, classpath {null}.
...
Caused by: com.puppycrawl.tools.checkstyle.api.CheckstyleException: cannot initialize module TreeWalker - Unable to find: config/app_checkstyle_suppressions.xml
...
Caused by: com.puppycrawl.tools.checkstyle.api.CheckstyleException: Unable to find: config/app_checkstyle_suppressions.xml
...
Caused by: java.io.FileNotFoundException: /Users/user/.gradle/daemon/5.1.1/config/app_checkstyle_suppressions.xml (No such file or directory)

Checkstyle或Gradle都在用户的系统 gradle目录中查找，而不是在我们自己的应用程序目录中查找。因此，我们让开发人员使用完整路径更新了checkstyle.xml：

   <module name="SuppressionXpathFilter">
            <property name="file" value="/Users/user/our_application/config/app_checkstyle_suppressions.xml"/>
            <property name="optional" value="false"/>
        </module>

然后一切正常。那么，为什么Checkstyle / Gradle无法识别config/app_checkstyle_suppressions.xml是正确的相对路径？为什么仅在一台开发机上会发生这种情况？

无法创建根模块：config {... config / strict_checkstyle.xml}，类路径{null}
