问题描述

（由于更新的问题/问题而更新了问题标题，请在底部查看我的更新注释！）：

Grails 2.2.0项目，通过' grails create-pom com.mycompany '为其创建了pom.xml。

pom.xml：

(Updated question title due to updated question/problem, please see my update notes at the bottom!):

I have a Grails 2.2.0 project, created the pom.xml for it via 'grails create-pom com.mycompany'.

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

Without modifications to the pom.xml, I run 'mvn package' with JDK 1.7 and getting the error below, while with JDK 1.6 it would work fine.

I see that the java version is set to 1.6 in grails-maven-plugin-2.2.0.pom, thus my question now: how to make the maven build for my grails project work with JDK 1.7? It looks as if the correct source and target level is set in maven-compiler-plugin (set to 1.6).

Folder ~/.m2/repository/grails-maven-plugin:

My environment:

• Maven 3.0.3
• Grails 2.2.0
• GRAILS_HOME set to my Grails directory
• JAVA_HOME set to my JDK 1.7 folder
• JDK 1.7.0_11

Relevant java tools section in my pom.xml:

<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>

解决方案

It seems to be a known issue and reportedly still happening in Grails 2.2.0 on Mac OS X.
