Eclipse + Maven：强制执行环境“JavaSE-1.6”而不是固定的JDK [英] Eclipse + Maven: force Execution Environment "JavaSE-1.6" instead of fixed JDK

问题描述

我正在使用Eclipse作为IDE和Maven，以保持所有依赖关系是最新的，并更新Eclipse项目。在Eclipse中，我通常将JRE系统库指定为任何Java项目的执行环境，通常是JavaSE-1.6。

在pom.xml中，我使用以下行：

 < plugin> 
< artifactId> maven-compiler-plugin< / artifactId> 
< version> 2.3.2< / version> 
< configuration> 
< source> 1.6< / source> 
< target> 1.6< / target> 
< / configuration> 
< / plugin> 
< plugin> 
< artifactId> maven-eclipse-plugin< / artifactId> 
< version> 2.8< / version> 
< configuration> 
< projectNameTemplate> [groupId]。[artifactId]< / projectNameTemplate> 
< downloadJavadocs> true< / downloadJavadocs> 
< wtpversion> 2.0< / wtpversion> 
< / configuration> 
< / plugin> 
  

这似乎让Maven选择了匹配1.6的JDK。它将系统库分配给项目的类路径。但是，它直接使用jdk1.6.20而不是JavaSE-1.6。

有没有办法让Maven使用JavaSE-1.6？

编辑：
这是我用来运行Maven的批处理文件：

  SET JAVA_HOME = C：\Programme\java\jdk1.6.0_20 
 SET MAVEN_HOME = C：\Programme\apache-maven-2.2.1 
 SET MAVEN_OPTS = -Xmx512m -XX：MaxPermSize = 128m 
 SET PATH =％JAVA_HOME％\bin;％MAVEN_HOME％\bin;％PATH％
 
 SET EXTRA_MVN_OPTS = -Dmaven。 test.skip = true 
 
 CD / D％〜dp0
 cmd / c mvn％EXTRA_MVN_OPTS％eclipse：clean eclipse：eclipse 
 cmd / c mvn％EXTRA_MVN_OPTS％clean安装
  

解决方案

可以通过设置classpath容器来实现。

 < plugin> 
< groupId> org.apache.maven.plugins< / groupId> 
< artifactId> maven-eclipse-plugin< / artifactId> 
< version> 2.8< / version> 
< configuration> 
< classpathContainers> 
< classpathContainer> 
 org.eclipse.jdt.launching.JRE_CONTAINER / org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType / JavaSE-1.6 
< / classpathContainer> 
< / classpathContainers> 
< / configuration> 
< / plugin>

  classpathContainers

I'm using Eclipse as IDE and Maven outside of it to keep all dependencies up to date and update the Eclipse-project as such. In Eclipse I usually specify the JRE system library as an execution environment for any Java-project, usually "JavaSE-1.6".

In the pom.xml I use the following lines:

        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
        <plugin>
            <artifactId>maven-eclipse-plugin</artifactId>
            <version>2.8</version>
            <configuration>
                <projectNameTemplate>[groupId].[artifactId]</projectNameTemplate>
                <downloadJavadocs>true</downloadJavadocs>
                <wtpversion>2.0</wtpversion>
            </configuration>
        </plugin>

This seems to let Maven pick a JDK matching 1.6. It assigns its system libraries to the classpath of the project. However, it uses jdk1.6.20 directly rather than JavaSE-1.6.

Is there a way to make Maven use JavaSE-1.6 instead?

EDIT: Here's the batch file that I use to run Maven:

SET JAVA_HOME=C:\Programme\java\jdk1.6.0_20
SET MAVEN_HOME=C:\Programme\apache-maven-2.2.1
SET MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=128m
SET PATH=%JAVA_HOME%\bin;%MAVEN_HOME%\bin;%PATH%

SET EXTRA_MVN_OPTS=-Dmaven.test.skip=true

CD /D "%~dp0"
cmd /c mvn %EXTRA_MVN_OPTS% eclipse:clean eclipse:eclipse
cmd /c mvn %EXTRA_MVN_OPTS% clean install

解决方案

You can do it by setting a classpath container.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-eclipse-plugin</artifactId>
    <version>2.8</version>
    <configuration>
        <classpathContainers>
           <classpathContainer>
    org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6
           </classpathContainer>
        </classpathContainers>
    </configuration>
</plugin>
