获取"<name>的POM无效,传递依赖(如果有的话)将无法在Eclipse中使用"

Question

我最近升级到JAXB 2.2.11并在Eclipse控制台中注意到以下消息:

10/15/14, 11:42:46 PM GMT+2: [INFO] Creating new launch configuration
10/15/14, 11:42:58 PM GMT+2: [INFO] C:\Projects\workspaces\mj2p\maven-jaxb2-plugin-project\tests\JAXB-1044

[ERROR] 'dependencyManagement.dependencies.dependency.systemPath' for com.sun:tools:jar must specify an absolute path but is ${tools.jar} @ 

让我感到困惑的是,我没有在控制台中收到此警告.该pom问题S还似乎是正确的.我确信我在控制台和Eclipse(m2e)中使用相同的Maven安装.存储库似乎也是正确的.

有谁碰巧知道,这可能是什么原因造成的？

请注意,这不是(几乎同名的)问题的重复:

• <name>的POM无效,传递依赖(如果有)将不可用

这个问题是关于控制台中的Maven执行与Eclipse之间的差异.

Answer 1

在pom对com.sun.xml.bind.jaxb-impl已com.sun.xml.bind:jaxb-parent拥有其母公司。

jaxb-parent pom 有以下部分：

<profile>
    <id>default-tools.jar</id>
    <activation>
        <file>
            <exists>${java.home}/../lib/tools.jar</exists>
        </file>
    </activation>
    <properties>
        <tools.jar>${java.home}/../lib/tools.jar</tools.jar>
    </properties>
</profile>
<profile>
    <id>default-tools.jar-mac</id>
    <activation>
    <file>
        <exists>${java.home}/../Classes/classes.jar</exists>
    </file>
    </activation>
    <properties>
        <tools.jar>${java.home}/../Classes/classes.jar</tools.jar>
    </properties>
</profile>

在您的Eclipse中，似乎没有激活任何配置文件，因为该配置文件${tools.jar}没有值。

一种可能是JAVA_HOME值设置不正确。

Answer 2

经过进一步调查后,我似乎遇到了与此问题相同的问题:

Maven没有正确选择JAVA_HOME

该解决方案感谢@rustyx(请给予好评这个问题的答案):

要解决此问题,您需要使用JDK中的JRE启动Eclipse,方法是将此类内容添加到eclipse.ini(之前-vmargs!):

-vm
C:\<your_path_to_jdk170>\jre\bin\javaw.exe
