Question

我正在尝试在Visual Studio 2015（TACO）项目中使用前置和后置构建。正如PreBuildEvent and PostBuildEvent on Visual Studio 2015 Tools for Apache Cordova中所述，我已将<Target>个元素添加到我的.jsproj文件中，以便它现在如图所示结束：

  <Import Project="_apacheCordovaProjectSourceItems.Targets" Condition="Exists('_apacheCordovaProjectSourceItems.Targets')" />
  <Target Name="BeforeBuild">
    <Exec Command="if $(ConfigurationName) == Release (echo ** Before Build **)" />  
    <Exec Command="attrib -R &quot;$(ProjectDir)\platforms\*.*&quot; /S" IgnoreExitCode="true" />
  </Target>
  <Target Name="AfterBuild">
    <Exec Command="if $(ConfigurationName) == Release (echo ** After Build **)" />  
    <Exec Command="if $(ConfigurationName) == Release (xcopy &quot;$(TargetDir)*.*&quot; &quot;$(SolutionDir)..\..\Binaries\$(PlatformName)\*.*&quot; /Y /S /E /F /I)" />
  </Target>
</Project>

我的问题是BeforeBuild和AfterBuild事件都在构建开始时触发

1>------ Build started: Project: MyProject, Configuration: Release Android ------
1>  ** Before Build **
1>  ** After Build **
1>  D:\Workspaces\Products\MyProduct\Projects\Main\Sources\Apps\MyProject\bin\Android\Release\android-release-unsigned.apk -> D:\Workspaces\Products\MyProduct\Projects\Binaries\Android\android-release-unsigned.apk
1>  D:\Workspaces\Products\MyProduct\Projects\Main\Sources\Apps\MyProject\bin\Android\Release\manifest-merger-release-report.txt -> D:\Workspaces\Products\MyProduct\Projects\Binaries\Android\manifest-merger-release-report.txt
1>  2 File(s) copied
1>  Your environment has been set up for using Node.js 0.12.2 (ia32) and npm.
1>   ... [Rest of output omitted] ...

有人可以解释为什么会这样，或者我如何在构建完成后运行post build事件？

将我的头撞到墙上一段时间之后，我放弃了Visual Studio AfterBuild事件，并使用了一个挂钩用于Cordo after_build。它在整个构建过程中稍早点火，但足以满足我的要求。我将发布其所需要的要点，以防其他人需要做类似的事情。

在Solution Explorer中找到config.xml，右键单击它并选择View Code
在config.xml中添加<hook>部分，如下所示
```
<platform name="android">
    <hook type="after_build" src="scripts/afterbuild-copy-to-drop.js" />
</platform>
```
在这里，我只是挂钩了一个Android版本的after_build事件。
现在在项目的根目录创建一个脚本文件夹，即与插件和www文件夹相同的级别。
在这里创建一个JavaScript文件，其名称与钩子定义中的src属性相匹配，即'afterbuild-copy-to-drop.js'。

在此脚本文件中编写所需的代码。这是我的

module.exports = function (ctx) {
    console.log('Executing custom "' + ctx.hook + '" hook for ' + ctx.opts.platforms);

    var path = ctx.requireCordovaModule('path'),
        shell = ctx.requireCordovaModule('shelljs');

    // make sure we are in a release build
    var isRelease = (ctx.cmdLine.indexOf('--configuration Release') >= 0);

    var solutionRoot = path.join(ctx.opts.projectRoot, '../..');
    var dropRoot = path.join(solutionRoot, '../../Binaries/Release/Apps');

    if (isRelease){
        if (ctx.opts.platforms == 'android') {

            var platformRoot = path.join(ctx.opts.projectRoot, 'platforms/android');
            var apkFileLocation = path.join(platformRoot, 'build/outputs/apk/android-release.apk');

            dropRoot = path.join(dropRoot, 'Android');
            var dropApkFileLocation = path.join(dropRoot, 'my-app.apk');

            console.log('------ Making directory \'' + dropRoot + '\'');
            shell.mkdir('-p', dropRoot);

            console.log('------ Copying \'' + apkFileLocation + '\' to ' + dropApkFileLocation + '\'');
            shell.cp('-f', apkFileLocation, dropApkFileLocation);
        }
    }

    console.log('Finished executing "' + ctx.hook + '" hook for ' + ctx.opts.platforms);
};
