Maven + Eclipse无法构建路径

Question

我在stackoverflow上找到了此解决方案。 Warning - Build path specifies execution environment J2SE-1.4

我得到了几乎相同的问题，但不是1-4我有1-6。不幸的是我不太了解这个配置。这对我来说是新事物。我正在尝试第二个解决方案来实现这个工作。我发现这个pom.xml的src中我的项目之下，它的XML看起来是这样的：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

      <scope>test</scope> 
     </dependency> 
    </dependencies> 

    <!-- Configure Build Process --> 
    <build> 
     <plugins> 
      <!-- Compiler plugin to use Java 1.6 compatiblity --> 
      <plugin>

       <artifactId>maven-compiler-plugin</artifactId> 
       <version>2.3.2</version> 
       <configuration> 
        <source>1.6</source> 
        <target>1.6</target> 
       </configuration> 
      </plugin> 

      <!-- Eclipse plugin to force download of source and JavaDoc jars --> 

      <plugin> 
       <groupId>org.apache.maven.plugins</groupId> 
       <artifactId>maven-eclipse-plugin</artifactId> 
       <version>2.8</version> 
       <configuration> 
        <wtpversion>2.0</wtpversion> 
        <downloadSources>true</downloadSources> 
        <downloadJavadocs>true</downloadJavadocs> 
       </configuration> 
      </plugin> 
     </plugins> 



    </build> 
</project> 

什么，我应该在哪里添加某事？我在Windows 7上使用Eclipse。我的Java版本是：1.8.0.25-b18像plugin和Maven和JUnit这样的单词以红色突出显示。我会很感激的帮助！

Answer 1

尝试

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <version>2.3.2</version> 
    <configuration> 
     <source>1.4</source> 
     <target>1.4</target> 
    </configuration> 
</plugin> 

然后用mvn eclipse:eclipse重新生成Eclipse项目。
