eclipse - 仅在 Eclipse 中获取 "The POM for is invalid, transitive dependencies (if any) will not be available"

Question

我最近升级到 JAXB 2.2.11 并在我的 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。 pom有问题的 s 似乎也是正确的。我确定我在控制台和 Eclipse ( m2e ) 中使用相同的 Maven 安装。存储库似乎也是正确的。

有没有人碰巧知道，这可能是什么原因造成的？

Please note that this is not a duplicate for (almost identically-named) question:

• The POM for <name> is invalid, transitive dependencies (if any) will not be available

This question is about the differences between Maven execution in the console and from the Eclipse.

Answer 1

pom为 com.sun.xml.bind.jaxb-impl有 com.sun.xml.bind:jaxb-parent有它的 parent 。
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，由于 ${tools.jar}，似乎没有一个配置文件被激活。没有值(value)。

一种可能是 JAVA_HOME值设置不正确。
