集成eclipse和maven時出現錯誤

Question

我是maven和eclipse配置的新手。我建立了我的Maven的路徑在日食

然後我做了一個項目運行配置在Eclipse

這裏是我的pom.xml的片段

<modelVersion>4.0.0</modelVersion> 
<groupId>package</groupId> 
<artifactId>myProject</artifactId> 
<packaging>war</packaging> 
<version>1.0-SNAPSHOT</version> 
<name>myProject</name> 
<url>http://maven.apache.org</url> 

現在，當我調試我的項目我得到一個錯誤，

Some problems were encountered while building the effective model for 
package:war:1.0-SNAPSHOT [WARNING] 
'build.plugins.plugin.version' for 
org.apache.maven.plugins:maven-compiler-plugin is missing. @ line 189, column 15 

在我的pom.xml文件中我有這樣

<build> 
<plugins> 
    <plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <configuration> 
     <source>1.6</source> 
     <target>1.6</target> 
    </configuration> 
    </plugin> 
</plugins> 

而且我得到錯誤

project pk.training.basitMahmood:myProject:war:1.0-SNAPSHOT: Failed to

但是我有所有這些dependicies在我的POM的項.xml，就像

<dependencies> 
<dependency> 
    <groupId>junit</groupId> 
    <artifactId>junit</artifactId> 
    <version>4.4</version> 
    <scope>test</scope> 
</dependency> 
<dependency> 
    <groupId>org.mockito</groupId> 
    <artifactId>mockito-all</artifactId> 
    <version>1.8.1</version> 
    <scope>test</scope> 
</dependency> 
<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>servlet-api</artifactId> 
    <version>2.5</version> 
    <type>jar</type> 
    <scope>compile</scope> 
</dependency> 
<dependency> 
    <groupId>commons-lang</groupId> 
    <artifactId>commons-lang</artifactId> 
    <version>2.5</version> 
    <type>jar</type> 
    <scope>compile</scope> 
</dependency> 
..... 
</dependencies> 

這裏是倉庫

<repositories> 
    <repository> 
     <id>maven2-repository.dev.java.net</id> 
     <url>http://download.java.net/maven/2</url> 
    </repository> 
    <repository>

     <id>maven2-apache</id> 
     <url>http://ftp.cica.es/mirrors/maven2/</url> 
    </repository> 

</repositories> 

爲什麼我收到這些錯誤？我如何解決它？

感謝

Answer 1

在這種情況下，最重要的一個是，你錯過了Maven的編譯器插件版本：

<build> 
<plugins> 
    <plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <version>3.1</version> 
    <configuration> 
     <source>1.6</source> 
     <target>1.6</target> 
    </configuration> 
    </plugin> 
</plugins> 

你爲什麼要定義這麼多資源庫，特別是Maven的1庫？如果您真的需要它們，只需使用Central即可定義其他存儲庫。

測試maven構建的最好方法是在命令行上執行該操作，如果這種做法完美地將其放入Eclipse中。
