使用Bower的聚合物会导致Cordova中的构建失败

Question

我正在使用凉亭下载和管理所有聚合物组件.但是,添加"bower_components"文件夹后,Cordova无法再成功构建.

:processDebugResources
      Unable to add 'C:\...\platforms\android\build\intermediates\assets\debug\www\bower_components\web-animations-js\web-animations.min.js.gz': file already in archive (try '-u'?)
ERROR: unable to process assets while packaging 'C:\...\platforms\android\build\intermediates\res\resources-debug.ap_'
ERROR: packaging of 'C:\...\platforms\android\build\intermediates\res\resources-debug.ap_' failed
:processDebugResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':processDebugResources'.

Error Code:

BUILD FAILED

这似乎是因为/ web-animations-js中的.gz文件.

无论如何,还有很多文件和文件夹应该被删除,例如那些"测试"和"演示"文件夹,当我用bower下载组件时包含这些文件和文件夹.

我该如何解决这个问题？

Answer 1

我不确定为什么 Cordova 的构建失败，但是回答有关删除测试/演示文件的第二个问题，您可以使用Cordova hooks。

我们在 Cordova 之上使用 Ionic Framework，这里有一篇关于一些 Cordova 钩子的有趣文章。

因此，我们使用的挂钩之一是030_clean_dev_files_from_platforms.js位于hooks/after_prepare目录中的一个名为的文件，其中包含以下内容：

#!/usr/bin/env node

/**
 * After prepare, files are copied to the platforms/ios and platforms/android folders.
 * Lets clean up some of those files that arent needed with this hook.

var fs = require('fs');
var path = require('path');


var deleteFolderRecursive = function(removePath) {
    if( fs.existsSync(removePath) ) {
        fs.readdirSync(removePath).forEach(function(file,index){
            var curPath = path.join(removePath, file);
            if(fs.lstatSync(curPath).isDirectory()) { // recurse
                deleteFolderRecursive(curPath);
            } else { // delete file
                fs.unlinkSync(curPath);
            }
        });
        fs.rmdirSync(removePath);
    }
};
