嘗試重建maven項目時出錯

Question

我是新手，有這樣的問題。 我知道maven在C：\「User \」文件夾下創建它的本地資源文件夾 ，當我創建我的項目（例如在eclipse中）並添加依賴關係時。 然後我將我的M2_Home存儲庫添加到構建路徑（C：\「User」\ m2）中。

經過這一切操作，我打開我的命令行並編寫mvn package。 Maven創建jar文件我開始它，一切看起來很好。

但有些時候我在電腦工作，我也沒有管理員的規則並不能在磁盤上創建文件夾C：

唯一的解決辦法是改變本地回購文件夾。我這樣做，並試圖重建我在家寫的項目。 Maven在命令行中向我展示了所有構建都是成功的。 我開始jar文件，並看到錯誤告訴我，我的應用程序無法找到庫（但當我檢查本地repo文件夾，我發現這個庫）。

那麼有人可以幫助我解決這類問題。

Answer 1

您已經創建了不包含罐子你需要的依賴關係。在這種情況下，你需要創建一個所謂的ueber-JAR可以通過使用maven-assembly-plugin (jar-with-dependencies)或通過maven-shade-plugin

<project> 
    [...] 
    <build> 
    [...] 
    <plugins> 
     <plugin> 
     <artifactId>maven-assembly-plugin</artifactId> 
     <version>2.4</version> 
     <configuration> 
      <descriptorRefs> 
      <descriptorRef>jar-with-dependencies</descriptorRef> 
      </descriptorRefs> 
     </configuration> 
     <executions> 
      <execution> 
      <id>make-assembly</id> <!-- this is used for inheritance merges --> 
      <phase>package</phase> <!-- bind to the packaging phase --> 
      <goals> 
       <goal>single</goal> 
      </goals> 
      </execution> 
     </executions> 
     </plugin> 
     [...] 
</project> 

Answer 2

我喜歡maven-shade-plugin了maven-assembly-plugin來完成。 他們做幾乎相同的事情，但maven-assembly-plugin是越野車。

maven-assembly-plugin有一個覆蓋文件的習慣，這會造成文件或其內容的丟失。

maven-shade-plugin通過簡單地附加它們來解決這個問題。
