集成eclipse和maven时出现错误

Question

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

然后我做了一个项目运行配置在Eclipse

这里是我的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> 

现在，当我调试我的项目我得到一个错误，

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文件中我有这样

<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> 

而且我得到错误

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

但是我有所有这些dependicies在我的POM的项.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>

为什么我收到这些错误？我如何解决它？

在这种情况下，最重要的一个是，你错过了Maven的编译器插件版本：

<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> 

你为什么要定义这么多资源库，特别是Maven的1库？如果您真的需要它们，只需使用Central即可定义其他存储库。

测试maven构建的最好方法是在命令行上执行该操作，如果这种做法完美地将其放入Eclipse中。
