Yui壓縮器文件在Jar包裝之前未刷新

Question

我使用Maven yui壓縮程序插件和Maven一個jar插件來創建一個容器js和css資源的jar文件。看起來，雖然，我的壓縮的CSS文件總是「一個編譯後面」，這意味着我必須編譯應用程序兩次，以接受一個CSS更改。這裏是我的構建POM的部分插件

當我檢查我的源代碼樹，我看到過壓縮CSS是存在的，但它不是在瓶子裏。我想比較一下，在單瓶包裝之前將文件「沖洗」出來。有沒有人見過這個？

例子：我已將此添加的style.css

.clear-both { 
    clear: both; 
} 

而在style.min.css源樹

.clear-both{clear:both;} 

但是，當我要求這個文件在服務器：

GET css/style.min.css 

該行不存在。

難道這涉及到與資源插件插件執行的順序：

[INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ MyApp --- 
[INFO] Using 'UTF-8' encoding to copy filtered resources. 
[INFO] Copying 661 resources 
[INFO] 
[INFO] --- yuicompressor-maven-plugin:1.1:compress (default) @ MyApp --- 
... 

Answer 1

是的，這是由於maven-resources-plugin在yuicompressor-maven-plugin之前執行的事實，因此您的縮小文件未被複制到最終的jar文件中。

重新排列階段將幫助您解決這個問題，但解決此問題的最佳方法是避免在源代碼樹中生成縮小/壓縮/編譯文件。這些文件不應該是源代碼樹的一部分，但應該生成到您的版本的輸出目錄中。使用Maven的${project.build.directory}（目標目錄）進行各種操作和處理。這也將確保所有生成的文件總是在Maven構建期間清理（mvn clean install）

看看下面的構建片段。我已經在必要時加入了評論。這段代碼是基於所有的咖啡腳本（.coffee文件），saas模板（.scss文件），其他css（未壓縮的.css文件），js（未壓縮的.js文件）和其他文件（比如圖像等）都存在於src/main/resources中。該片段只會封裝縮小的js和css，而未壓縮的js/css將不會打包到jar中。

如果你想測試這個，在你用這個代碼執行任何maven構建之前，先從src \ main \ resources中刪除所有生成的css文件，js文件和縮小文件。

參考：看一看相在Maven default lifecycle

Answer 2

答案是把CoffeeScript的，無禮的話，和YUI壓縮的過程中源相

<phase>process-sources</phase>
