Maven build for Grails 2.2.0 app fails with JDK 1.7: Could not find artifact com.sun:tools:jar:1.6

(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.

$ java -version

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:

enter image description here

My environment:

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>

The problem is that the grails-maven-plugin says that it needs something in JDK6:

tail -n20 ~/.m2/repository/org/grails/grails-maven-plugin/2.0.3/grails-maven-plugin-2.0.3.pom
    <profile>
        <id>jdk_mac</id>
        <activation>
            <os>
                <family>mac</family>
            </os>
        </activation>
        <dependencies>
            <dependency>
                <groupId>com.sun</groupId>
                <artifactId>tools</artifactId>
                <version>1.6</version>
                <scope>system</scope>
                <systemPath>${java.home}/bundle/Classes/classes.jar</systemPath>
            </dependency>
        </dependencies>
    </profile>
</profiles>

The solution is to copy the JDK6 classes.jar into your current JDK. Fortunately, JDK7 uses a different directory structure, so there should not be any conflict.

sudo mkdir -p /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/bundle/Classes
sudo cp /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Classes/classes.jar /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/bundle/Classes/

UPDATE

As mentioned by @Mathias this was a bug in the Grails Maven plugin. The issue has been fixed and all works fine in Grails 2.2.1.

I can definitely use mvn package here with Grails 2.2.0 from Homebrew, *GRAILS_HOME* unset.

My configuration is Maven 3.0.3 with Grails 2.2.0, on OSX.

I created a "blank" vanilla application without any trouble and packaged it.

grails create-app stf && cd stf
grails create-pom com.rimerosolutions.grails
mvn package

In my pom.xml, the version of grails-maven-plugin is set to ${grails.version}.

I'm running OSX, looks like you're running it too.

  • Are you using a private maven repository? If so, try to double-check the grails-maven-plugin artifact in there.
  • If not, just try to clear your ~/.m2/repository contents for grails-maven-plugin. rm -rf that specific plugin cache.

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