findbugs，retrolambda和Android

Question

我正在使用Android studio 1.4.1，我正在尝试设置findbug，但是即使用R和Manifest设置排除xml，也仍然会对它们进行分析。

我想：

1. 用android安装findbugs，以避免R和所有这些生成的东西，比如ViewBinder和Lambda。

分级文件：

apply plugin: 'findbugs'
apply plugin: 'pmd'

findbugs {
  ignoreFailures = true
  reportsDir = file("$project.buildDir/outputs/")
  reportLevel = "low"
  effort = "max"
  excludeFilter = file("../setup/findbugs-exclude.xml")
}

pmd {
  ignoreFailures = true
  reportsDir = file("$project.buildDir/outputs/")
}

task findbugs(type: FindBugs, dependsOn: assembleDebug) {
  description 'Run findbugs'
  group 'verification'

  classes = fileTree("build/intermediates/classes/debug/")
  source = fileTree('src/main/java')
  classpath = files()

  reports {
    xml.enabled = false
    html.enabled = true
  }
}

task pmd(type: Pmd, dependsOn: assembleDebug) {
  description 'Run pmd'
  group 'verification'

  ruleSets = ["java-basic", "java-braces", "java-strings", "java-design", "java-unusedcode"]
  source = fileTree('src/main/java')

  reports {
    xml.enabled = false
    html.enabled = true
  }
}

check.doLast {
  project.tasks.getByName("findbugs").execute()
  project.tasks.getByName("pmd").execute()
}

findbugs-exclude.xml

<?xml version="1.0" encoding="UTF-8"?>
<FindBugsFilter>
  <Match>
    <Class name="~.*\.R\$.*" />
  </Match>
  <Match>
    <Class name="~.*\.Manifest\$.*" />
  </Match>
</FindBugsFilter>

Answer 1

也许这个能帮上忙。只需将以下代码添加到findbugs expde.xml中：

<Match>
    <Bug code="UPM" />
    <Class name="~.*\$\$Lambda\$.*"/>
</Match>
