Maven的編譯器錯誤

Question

你好，我已經得到了從我的電腦建立就好了，但是我遇到的其他環境這個問題（服務器）的一個項目：

----------------------------------------------------- 
[INFO] ------------------------------------------------------------------------ 
[ERROR] BUILD ERROR 
[INFO] ------------------------------------------------------------------------ 
[INFO] Internal error in the plugin manager executing goal 'org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile': Unable to load the mojo 'org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile' in the plugin 'org.apache.maven.plugins:maven-compiler-plugin'.

這有做與Maven插件編譯東西我認爲，在這種情況下可以做些什麼？

與-e執行每貝希建議：

Answer 1

我建議運行

mvn -v 

發現，如果你正在使用兩臺機器上不同的Maven版本。

同時我會建議升級到更新版本的編譯器插件。 2.0.2是非常古老的。如果不是最新的3.0，至少升級到2.3.2甚至2.5.1。

此外，我將指定源和目標的語言水平（例如Java 7的下面），你需要使你最終會得到這樣的事情

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <version>3.0</version> 
    <configuration> 
    <source>1.7</source> 
    <target>1.7</target> 
    </configuration> 
</plugin> 

這應該要麼修復它，或者至少給你更多信息請看下面的內容。

Answer 2

我在做maven clean時遇到過類似的問題。
它使用maven-clean-plugin 2.2版。
添加以下到我的構建和解決的問題：

<plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-clean-plugin</artifactId> 
     <version>2.5</version> 
</plugin>
