Question

我不确定为什么要花很长时间找出并解决问题。在进行升级之前，一切都运行良好。这是build.gradle文件：

apply plugin: 'com.android.application'
apply from: '../config/quality/quality.gradle'

从Android Studio升级推荐后，我得到了这个。

这是quality.gradle：

**

 *
 * Gradle tasks added:
 * - checkstyle
 * - findbugs
 * - pmd

 * The three tasks above are added as dependencies of the check task so running check will
 * run all of them.

Answer 1

第一个问题是由以下原因引起的：

classes = file("$project.rootDir/app/build/intermediates/classes")

无效，因为它将File传递给期望FileCollection的属性。而不是使用Project.file，而应在此处使用Project.files。

我首先要解决这个问题，看看是否经过适当的评估才能使构建通过。

Answer 2

我终于修复了它，它是需要在quality.gradle文件中所有目标前面放置的“文件”方法名称：

/**
 * Set up Checkstyle, Findbugs and PMD to perform extensive code analysis.
 *
 * Gradle tasks added:
 * - checkstyle
 * - findbugs
 * - pmd
 *
 * The three tasks above are added as dependencies of the check task so running check will
 * run all of them.
 */

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

dependencies {
    checkstyle 'com.puppycrawl.tools:checkstyle:6.5'
}

def qualityConfigDir = "$project.rootDir/config/quality";
def reportsDir = "$project.buildDir/reports"

check.dependsOn 'checkstyle', 'findbugs', 'pmd'

task checkstyle(type: Checkstyle, group: 'Verification', description: 'Runs code style checks') {
    configFile file("$qualityConfigDir/checkstyle/checkstyle-config.xml")
    source 'src'
    include '**/*.java'
    exclude '**/model/**'
    exclude '**/AppLogger.java'
    reports {
        xml.enabled = true
        html.enabled = false
        xml {
            destination file("$reportsDir/checkstyle/checkstyle.xml")
        }
        html {
            destination file("$reportsDir/checkstyle/checkstyle.html")
        }
    }

    classpath = files()
}

task findbugs(type: FindBugs,
        group: 'Verification',
        description: 'Inspect java bytecode for bugs',
        dependsOn: ['compileDebugSources', 'compileReleaseSources']) {

    ignoreFailures = false
    effort = "max"
    reportLevel = "high"
    excludeFilter = new File("$qualityConfigDir/findbugs/android-exclude-filter.xml")
    classes = files("$project.rootDir/app/build/intermediates/classes")

    source 'src'
    include '**/*.java'
    exclude '**/gen/**'

    reports {
        xml.enabled = true
        html.enabled = false
        xml {
            destination file("$reportsDir/findbugs/findbugs.xml")
        }
        html {
            destination file("$reportsDir/findbugs/findbugs.html")
        }
    }

    classpath = files()
}

    ruleSetFiles = files("$qualityConfigDir/pmd/pmd-ruleset.xml")
    ignoreFailures = false

    source 'src'
    include '**/*.java'
    exclude '**/gen/**'
    exclude '**/model/**'

    reports {
