在 android gradle 3.6.1 中運行構建任務后未生成 Jar

Question

我的構建 jar 任務在 3.5.3 級中運行良好，但在 3.6.1 級中不起作用。 我檢查了我的構建文件，但是，奇怪地缺少/build/intermediates/packaged-classes/目錄。

gradle 腳本：

task buildJar(dependsOn: ['build'], type: Jar) {
    doFirst {
        manifest {
            attributes 'Jar-VersionName': jarVersionName
            attributes 'Jar-VersionCode': jarVersionCode
        }
    }
    from zipTree(file('build/intermediates/packaged-classes/release/classes.jar'))
    appendix = ""
    baseName = "pp"
    version = jarVersionName + "_" + jarVersionCode
    classifier = "release"
    extension = "jar"
    destinationDir = file('build/libs/')
}

//dx --dex --output=target.jar origin.jar
task buildDex(dependsOn: ['buildJar'], type: Exec) {
    workingDir buildDir.absolutePath + "/libs"
    executable "dx"
    args "--dex"
    args "--output=" + buildJar.archiveName
    args buildJar.archiveName
}

錯誤日志：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':p2p:buildJar'.
> Cannot expand ZIP '/Users/william/AndroidStudioProjects/Work/lib_plugin/project/build/intermediates/packaged-classes/release/classes.jar' as it does not exist.

我環顧四周，顯然我可以在這些解決方案之間做出選擇，但它們對我來說太舊了。

升級Android Studio后沒有發布包文件夾

.jar 文件未在 android studio 中生成

Gradle不生成jar

那么，生成的jar的新路徑在哪里呢？

Answer 1

我找到了！ 當我將 gradle 版本升級到 4.0 時，我在build/intermediates/aar_main_jar/release/classes.jar路徑中找到了class.jar 。

因此，完整的構建任務代碼如下：

def jarPath = buildDir.absolutePath + "/libs"
def jarBaseName = "plugin"

task buildJar(dependsOn: ['build'], type: Jar) {
    doFirst {
        manifest {
            attributes 'Jar-VersionCode': jarVersionCode
        }
    }
    from zipTree(file('build/intermediates/aar_main_jar/release/classes.jar'))
    // [archiveBaseName]-[archiveAppendix]-[archiveVersion]-[archiveClassifier].[archiveExtension]
    archiveBaseName = jarBaseName
    archiveAppendix = null
    archiveVersion = "$jarVersionName-$jarVersionCode"
    archiveClassifier = "release"
    archiveExtension = "jar"
    destinationDirectory = file(jarPath)
}

// dx --dex --output=target.jar origin.jar
task buildDex(dependsOn: ['buildJar'], type: Exec) {
    workingDir jarPath
    executable "dx"
    args "--dex"
    args "--output=" + buildJar.archiveFileName.get()
    args buildJar.archiveFileName.get()
}
