CQ5 - eclipse and maven setup

[Former Community Member]

Hi All,

I have setup my CQ workspace in eclipse and using maven to build the project. I am trying to compile a test java file:

package com.mercer.taglibs.tags; import com.day.cq.wcm.api.Page; public class HelloPerson { private Page personPage; public static final String PN_PERSON_NAME = "personName"; public HelloPerson(Page personPage) { this.personPage = personPage; } public String getHelloMessage() { String personName = personPage.getProperties().get(PN_PERSON_NAME).toString(); return personName != null ? personName : "--empty--"; } }

I have provided the dependency in parent

<dependency> <groupId>com.day.cq.wcm</groupId> <artifactId>cq-wcm-core</artifactId> <version>5.6.4</version> <scope>provided</scope> </dependency>

pom.xml like this:

and referencing it in the child pom.xml like this:

<dependency> <groupId>com.day.cq.wcm</groupId> <artifactId>cq-wcm-core</artifactId> </dependency>

the error I am getting is:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project mercer-cq-package-bundle: Compilation failure: Compilation failure:

Follow this community article that walks you through how to use Maven and Eclipse to build an OSGi bundle that you can deploy to Adobe Experience Manager:

Hi HTH,

Thank you for your response. I have gone through that already and used the dependency the same way as in the link you sent. I am not able to understand what more dependency I need to use. I used CQ in-built dependency checker to determine the dependency of com.day.cq.wcm.api. Declared it and then trying to compile my code. Do let me know if I need to provide some further information.

Regards,

Ankit

Did you follow the step by step and create the Maven project? 

When you build the OSGi in this article -- you will get this result:

The POM file that you use is and includes all dependencies is in the article. 

[smacdonald2008]

Also - as specified in the POM in the article - you need to include this dependency to use com.day.cq.wcm:

<dependency>
            <groupId>com.day.cq</groupId>
            <artifactId>cq-commons</artifactId>
            <version>5.5.0</version>
            <scope>provided</scope>
        </dependency>

Hope this helps

Hi HTH,

I am already using this dependency though with a different version:

<dependency>
             <groupId>com.day.cq</groupId>
            <artifactId>cq-commons</artifactId>
            <version>5.6.2</version>
            <scope>provided</scope>
            </dependency>

Do you think version make a difference? Also, for your reference I am including the whole set of dependencies I am using:

<dependencies> <dependency> <groupId>org.osgi</groupId> <artifactId>org.osgi.core</artifactId> <version>4.2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.osgi</groupId> <artifactId>org.osgi.compendium</artifactId> <version>4.2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.felix</groupId> <artifactId>org.apache.felix.scr.annotations</artifactId> <version>1.6.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>biz.aQute</groupId> <artifactId>bndlib</artifactId> <version>1.43.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.5.10</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.jcr</groupId> <artifactId>jcr</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.api</artifactId> <version>2.2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.jcr.api</artifactId> <version>2.1.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.8.1</version> <scope>test</scope> </dependency> <!-- adding dependencies by AnkitC::Start --> <dependency> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.jcr.jcr-wrapper</artifactId> <version>2.0.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.day.cq</groupId> <artifactId>cq-commons</artifactId> <version>5.6.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.day.cq.wcm</groupId> <artifactId>cq-wcm-commons</artifactId> <version>5.6.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.day.cq.wcm</groupId> <artifactId>cq-wcm-api</artifactId> <version>5.6.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.day.commons</groupId> <artifactId>day-commons-jstl</artifactId> <version>1.1.4</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.day.cq.wcm</groupId> <artifactId>cq-wcm-taglib</artifactId> <version>5.6.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.scripting.jsp.taglib</artifactId> <version>2.1.8</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.adobe.granite</groupId> <artifactId>com.adobe.granite.xssprotection</artifactId> <version>5.5.22</version> <scope>provided</scope> </dependency> <!-- dependency provided by AnkitC::Start --> <dependency> <groupId>com.adobe.granite</groupId> <artifactId>com.adobe.granite.ui.commons</artifactId> <version>5.5.60</version> <scope>provided</scope> </dependency> <!-- dependency provided by AnkitC::Stop --> <dependency> <groupId>com.day.cq.wcm</groupId> <artifactId>cq-wcm-core</artifactId> <version>5.6.4</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <!-- adding dependencies by AnkitC::Stop --> </dependencies>

Let me know if you think the dependencies doesnt look ok.

Thanks,

Did you add this repository to your POM:

<repositories>
        <repository>
            <id>adobe</id>
            <name>Adobe Public Repository</name>
            <url>http://repo.adobe.com/nexus/content/groups/public/</url>
            <layout>default</layout>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>adobe</id>
            <name>Adobe Public Repository</name>
            <url>http://repo.adobe.com/nexus/content/groups/public/</url>
            <layout>default</layout>
        </pluginRepository>
    </pluginRepositories>       

[Former Community Member]

Yes, I have them in my pom.xml like this:

<repository>
            <id>adobe</id>
            <name>Adobe Public Repository</name>
            <url>http://repo.adobe.com/nexus/content/groups/public/</url>
            <layout>default</layout>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>adobe</id>
            <name>Adobe Public Repository</name>
            <url>http://repo.adobe.com/nexus/content/groups/public/</url>
            <layout>default</layout>
        </pluginRepository>
    </pluginRepositories>

I took your POM and failed for me too -- the issue is with your POM file.

I modified your POM and its working now:
