我尝试将spotbug应用到一个大型开源项目elasticsearch上，该项目的结构非常复杂，通过将spotbug配置为 allprojects 在根目录下的build.gradle文件中。
问题是：它没有为所有子项目生成报告。

复制步骤

渐变版本：6.6.1
在您的计算机上安装java14。
从github克隆elasticsearch。
修改第一个 allprojects 在 build.gradle 在根目录下，如下所示：

plugins {
    ...
    id "com.github.spotbugs" version "4.6.0"
}

// common maven publishing configuration
allprojects {
    group = 'org.elasticsearch'
    version = VersionProperties.elasticsearch
    description = "Elasticsearch subproject ${project.path}"

    apply plugin: "com.github.spotbugs"
    spotbugs {
        toolVersion = '4.1.4'
        ignoreFailures = false
        showStackTraces = true
        showProgress = true
        effort = 'default'
        visitors = [ 'FindFinalizeInvocations','FindRoughConstants','FindRefComparison','FindUnrelatedTypesInGenericContainer','FormatStringChecker','DontCatchIllegalMonitorStateException','InfiniteRecursiveLoop','InheritanceUnsafeGetResource','Naming','SerializableIdiom','StaticCalendarDetector','DumbMethods' ]

        maxHeapSize = '4g'
        reportLevel = 'low'
    }
}

编译源文件和测试文件

gradle clean classes testClasses -Dorg.gradle.java.home=/usr/lib/jvm/java-14-openjdk

执行SpotBug的任务

gradle spotbugsMain spotbugsTest -Dorg.gradle.java.home=/usr/lib/jvm/java-14-openjdk

计数xml报告

find . -path "*build/reports/spotbugs/*.xml" | wc -l  # output: 22

结果

我注意到没有为某些子项目生成xml报告。例如，如下面的树所示，subproject client作为xml报告，但是x-pack没有。

.
├── ...
├── client
│   └── benchmark
│       ├── build
│       │   ├── ...
│       │   └── reports
│       │       └── spotbugs
│       │           └── main.xml
│       ├── build.gradle
│       ├── ...
│       └── src
│    
└── x-pack
    ├── build.gradle
    └── plugin
        └── sql
            ├── build.gradle
            ├── other_sub_modules
            └── src

然后，我将目录更改为子项目x-pack:plugin：sql，并修改了其 build.gradle 具体如下：

allprojects {
  tasks.register("checkNoBwc") {
    dependsOn tasks.withType(Test).matching { it.name.contains('bwc') == false }
  }
   apply plugin: "com.github.spotbugs"
  spotbugs {
      toolVersion = '4.1.4'
      ignoreFailures = false
      showStackTraces = true
      showProgress = true
      effort = 'default'
      includeFilter = file("/home/xiaowen/Project/rbugs_experiments/build_projects/spotbugs-includeFilter.xml")
      visitors = [ 'FindFinalizeInvocations','FindRoughConstants','FindRefComparison','FindUnrelatedTypesInGenericContainer','FormatStringChecker','DontCatchIllegalMonitorStateException','InfiniteRecursiveLoop','InheritanceUnsafeGetResource','Naming','SerializableIdiom','StaticCalendarDetector','DumbMethods' ]
      maxHeapSize = '4g'
      reportLevel = 'low'
  }
}

在执行spotbug任务之后，我得到了带有bug示例的xml报告。

问题

只在根目录中配置spotbug时 build.gradle ，为什么子…子项目，如sql，被忽略？
如何通过修改覆盖所有子项目 build.gradle 是不是尽可能少？
更多信息：部分结果 gradle -q projects -Dorg.gradle.java.home=/usr/lib/jvm/java-14-openjdk 从中我们知道gradle成功地了解了sql的子项目。
