Grails 2.2.0 应用程序的 Maven 构建因 JDK 1.7 : Could not find artifact com. sun :tools:jar:1. 6 而失败

Question

(由于更新的问题/问题更新了问题标题，请参阅底部的更新说明!):

我有一个 Grails 2.2.0 项目，通过“grails create-pom com.mycompany”为其创建了 pom.xml。

pom.xml:http://pastebin.com/AVahZjZF

在不修改 pom.xml 的情况下，我使用 JDK 1.7 运行“mvn package”并在使用 JDK 1.6 时出现以下错误> 它会很好地工作。

$ java -version

$ mvn -version

我看到 grails-maven-plugin-2.2.0.pom 中的 java 版本设置为 1.6，因此我现在的问题是:如何使我的 grails 项目的 maven 构建与 JDK 1.7 一起工作？看起来好像在 maven-compiler-plugin 中设置了正确的源和目标级别(设置为 1.6)。

文件夹 ~/.m2/repository/grails-maven-plugin:

我的环境:

• maven 3.0.3
• Grails 2.2.0
• GRAILS_HOME 设置为我的 Grails 目录
• JAVA_HOME 设置为我的 JDK 1.7 文件夹
• JDK 1.7.0_11

我的 pom.xml 中的相关 java 工具部分:

<profiles>
    <profile>
        <id>tools</id>
        <activation>
            <property>
                <name>java.vendor</name>
                <value>Sun Microsystems Inc.</value>
            </property>
        </activation>
        <dependencies>
            <dependency>
                <groupId>com.sun</groupId>
                <artifactId>tools</artifactId>
                <version>${java.version}</version>
                <scope>system</scope>
                <systemPath>${java.home}/../lib/tools.jar</systemPath>
            </dependency>
        </dependencies>
    </profile>
</profiles>

这似乎是一个已知问题，据报道仍在 Mac OS X 上的 Grails 2.2.0 中发生。
