Using plain groovy console in vault-upgrade-hook - mi...

[bartek__w]

Hi, I am trying to use vault upgrade hook with plain groovy (not groovy console) to work with latest AEM as a Cloud Service instance (local setup, I know that this will not work on AMS isntance at the moment due to issue with FileVault, for more see this link)

As I read to do so I need to install Apache Sling Scripting Groovy and all it's dependencies:

// https://mvnrepository.com/artifact/org.apache.sling/org.apache.sling.scripting.groovy/1.2.0
<dependency>
    <groupId>org.apache.sling</groupId>
    <artifactId>org.apache.sling.scripting.groovy</artifactId>
    <version>1.2.0</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.codehaus.groovy/groovy -->
<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy</artifactId>
    <version>3.0.1</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.codehaus.groovy/groovy-json -->
<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy-json</artifactId>
    <version>3.0.1</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.codehaus.groovy/groovy-templates -->
<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy-templates</artifactId>
    <version>3.0.1</version>
</dependency>

Unfortunately when I install json bundle I got the following error:

org.apache.felix.log.LogException: org.osgi.framework.BundleException: Unable to resolve groovy-json [551](R 551.0): missing requirement [groovy-json [551](R 551.0)] osgi.extender; (osgi.extender=osgi.serviceloader.registrar) Unresolved requirements: [[groovy-json [551](R 551.0)] osgi.extender; (osgi.extender=osgi.serviceloader.registrar)]

Do you have an idea what might be missing here ? Thanks for your help 🙂

I found a blog post https://blog.osgi.org/2013/02/javautilserviceloader-in-osgi.html that addresses the issue I had below. To fix that I added the following bundles to the instance: 

            <!-- Dependencies needed to run Vault upgrade hook with plain groovy -->
            <dependency>
                <groupId>org.apache.sling</groupId>
                <artifactId>org.apache.sling.scripting.groovy</artifactId>
                <version>1.2.0</version>
            </dependency>
            <dependency>
                <groupId>org.codehaus.groovy</groupId>
                <artifactId>groovy</artifactId>
                <version>3.0.1</version>
            </dependency>
            <dependency>
                <groupId>org.codehaus.groovy</groupId>
                <artifactId>groovy-templates</artifactId>
                <version>3.0.1</version>
            </dependency>
            <dependency>
                <groupId>org.codehaus.groovy</groupId>
                <artifactId>groovy-json</artifactId>
                <version>3.0.1</version>
            </dependency>
            <!-- Dependencies below needed because of issue wth groovy-json bundle -->
            <!-- https://blog.osgi.org/2013/02/javautilserviceloader-in-osgi.html -->
            <dependency>
                <groupId>org.apache.aries.spifly</groupId>
                <artifactId>org.apache.aries.spifly.dynamic.bundle</artifactId>
                <version>1.3.3</version>
            </dependency>
            <!-- Dependencies below needs to be provided for org.apache.aries.spifly.dynamic.bundle-->
            <dependency>
                <groupId>org.ow2.asm</groupId>
                <artifactId>asm</artifactId>
                <version>9.1</version>
            </dependency>
            <dependency>
                <groupId>org.ow2.asm</groupId>
                <artifactId>asm-commons</artifactId>
                <version>9.1</version>
            </dependency>
            <dependency>
                <groupId>org.ow2.asm</groupId>
                <artifactId>asm-util</artifactId>
                <version>9.1</version>
            </dependency>
            <dependency>
                <groupId>org.ow2.asm</groupId>
                <artifactId>asm-tree</artifactId>
                <version>9.1</version>
            </dependency>
            <dependency>
                <groupId>org.ow2.asm</groupId>
                <artifactId>asm-analysis</artifactId>
                <version>9.1</version>
            </dependency>

Installing those bundles fixed the issue - now all required bundles are active and I groovy script is executed once package with upgrade hook is installed. I am not sure whether this is the right way to go though - adding so many dependencies to make this work seems wrong 🙂

@bartek__w, thank you for sharing the answer with community. This would help in posterity. Looking forward for more contribution form you.

Also using groovy-all package can help here, then issue with groovy-json is not showing. The only problem is to find proper version 🙂
