将 Android Gradle 插件从 3.1.3 升级到 3.2.0 后,FindBugs 停止工作

FindBugs stopped working after upgrading Android Gradle Plugin from 3.1.3 to 3.2.0

我在 Android 项目中使用 FindBugs 进行静态代码分析。设置如下:

quality.gradle

plugins.apply('findbugs')

task findbugs(type: FindBugs) {
    ignoreFailures = false
    effort = 'max'
    reportLevel = 'high' // Report only high priority problems.

    classes = files("${project.projectDir}/build/intermediates/classes")
    source = fileTree('src/main/java')

    classpath = files()

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

    excludeFilter = rootProject.file('quality/findbugs.xml')
} 

build.gradle:

subprojects {
    afterEvaluate {
        project.apply from: '../quality/quality.gradle'
        tasks.findByName('findbugs').dependsOn('assemble')
        tasks.findByName('check').dependsOn('findbugs')
    }
}

但是在我将 Gradle Android 插件从 3.1.3 升级到 3.2.0 之后,构建开始失败:

./gradlew clean build

> Task :app:findbugs FAILED
No files to be analyzed

...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:findbugs'.
> Failed to run Gradle FindBugs Worker
   > Process 'Gradle FindBugs Worker 6' finished with non-zero exit value 1

降级到 3.1.3 使构建再次通过。我没有在 Gradle Android 插件的 changelog 中找到任何相关内容。谁能指出我的插件或我的设置有什么问题吗?

经过短暂的调查,我发现 Java class 个文件的位置已从 build/intermediates/classes 更改为 build/intermediates/javac。新的 FindBugs 配置:

task findbugs(type: FindBugs) {
    ...
    classes = files("${project.projectDir}/build/intermediates/javac")
   ...
} 

奇怪的是 Android Gradle 插件 changelog, or in the Gradle changelog.

中没有提到这个重大变化
