Question

我有一个复杂的Android项目，该项目由多个Java和C ++模块组成，并使用多个构建工具（例如CMake，swig）。使用./gradlew clean assembleDebug从命令行构建时，项目的构建就很好，但从Android Studio构建时，则无法构建。我清理，使缓存无效，已同步等无济于事。

要注意的是：该项目在Android Studio（在Ubuntu（17. *和18. *）等其他系统上也可以很好地构建，但在MacOS（10.13，如果我没记错的话还可以更早）上失败）。

这是Android Studio报告的错误：

在命令行上：

“ runSwig”任务的定义如下所示：

task runSwig(type: Exec) {
    commandLine 'swig'

    doFirst {
        coreWrapperDir.mkdirs()
    }

    def swigFileCore = "${projectDir}/src/" + "swig.i"
    def headerFiles = "${projectDir}/include"
    def swigWrapFile = 'src/swig_wrap.cxx'

    inputs.file swigFileCore
    inputs.dir headerFiles
    outputs.dir coreWrapperDir.absolutePath
    outputs.file swigWrapFile

    // this write the generated swig C++ file to "${projectDir}/src"
    args '-c++', '-java', '-package', javaPackage, '-noexcept', '-outdir', coreWrapperDir.absolutePath, "-I${headerFiles}", '-o', swigWrapFile, swigFileCore
}

该日志表明Android Studio在当前工作目录中查找swig，而不是在$ PATH中查找它，但是对于如何告诉Android Studio在哪里查找，我一无所知。有什么想法吗？

Cannot run program "swig" (in directory "/Users/tom/workspace/indoors-scripts/setup-scripts/workspace-android/IndoorsAndroid/IndoorsLocator")

Answer 1

您是否已在build.gradle中添加此行？

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn runSwig
}

无论如何，您可以参考使用swig的github项目：https://github.com/sureshjoshi/android-ndk-swig-example

需要进行一些调试才能获取有关该问题的更多信息。将以下代码添加到build.gradle模块的IndoorsLocator文件中，然后再次运行。这应该打印路径环境变量，并运行一个Java命令，我假设它也在路径内。然后执行gradle同步并编译或运行代码。打开第一个镜像中的构建窗口，并在构建停止时，在testPath列表中找到Run tasks并共享其输出。或更优选地，如下图所示，将Build切换为文本视图并共享完整的日志。通过命令对其进行测试也将有助于确保其按预期运行。

tasks.whenTaskAdded { addedTask ->
    if (addedTask.name.startsWith("preDebugBuild")) {
        addedTask.dependsOn 'testPath'
    }
}

task testPath {
    mustRunBefore 'checkDebugManifest'
    doLast {
        exec {
            commandLine 'echo', '$PATH'
        }
        exec {
            commandLine 'java', '-version'
        }
    }
}

根据您的第一条评论，这是一个奇怪的结果！应该使用Java，因此必须以某种方式设置$ PATH，但是echo $PATH无效。更新了代码，以进一步解决问题。

tasks.whenTaskAdded { addedTask ->
    if (addedTask.name.startsWith("preDebugBuild")) {
        addedTask.dependsOn 'testPath'
    }
}

task testPath {
    doLast {
        exec {
            commandLine 'printenv'
        }
        exec {
            commandLine 'which', 'java'
        }
        exec {
            commandLine 'which', 'swig'
        }
    }
}

PS：我在mustRunBefore上的错误，这个错误不存在，我加了意外！

事实证明，这是由于OSX中的“错误”引起的：https://github.com/gradle/gradle/issues/5631#issuecomment-401775152

我没有找到一种方法可以轻松地针对最新版本的OSX（https://apple.stackexchange.com/questions/106355/setting-the-system-wide-path-environment-variable-in-mavericks）对其进行修复，但是通过在build.gradle中对路径进行硬编码来解决该问题：

task runSwig(type: Exec) {
    // workaround for OSX, see https://stackoverflow.com/q/51383822/198996
    File testFile = new File('/usr/local/bin/swig');
    if (testFile.isFile()) {
        commandLine '/usr/local/bin/swig'
    } else {
        commandLine 'swig'
    }
}

如果您问我，这是一个糟糕的解决方法，所以我很乐意将悬赏奖励给提出更清洁解决方案的人。
