Maven building a jar, not an AMP

mangar — Sat, 13 Feb 2021 01:05:49 GMT

I am using alfresco 6.2 community. I used the AIO archtype. But when I "mvn clean install -DskipTests" All I get is a .jar file in the target directory, not an AMP. How do I fix this?

By default jar based extensions are built. In order to get amps along with jars, you need to uncomment the "maven-assembly-plugin" plugin. Take a look at the parent pom.xml in your project and find the below given plug-in.

Example for your reference: https://github.com/abhinavmishra14/alfresco-mimetype-blocker/blob/master/pom.xml#L125

              <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-assembly-plugin</artifactId>
                    <version>2.6</version>
                    <executions>
                        <execution>
                            <id>build-amp-file</id>
                            <phase>package</phase>
                            <goals>
                                <goal>single</goal>
                            </goals>
                            <configuration>
                                <appendAssemblyId>false</appendAssemblyId>
                                <descriptor>src/main/assembly/amp.xml</descriptor>
                            </configuration>
                        </execution>
                    </executions>
                    <dependencies>
                        <dependency>
                            <groupId>org.alfresco.maven.plugin</groupId>
                            <artifactId>alfresco-maven-plugin</artifactId>
                            <version>${alfresco.sdk.version}</version>
                        </dependency>
                    </dependencies>
               </plugin>

When using any external or different amp module in your project you need to add the dependency with following:

<exclusions>
       <exclusion>
         <groupId>*</groupId>
         <artifactId>*</artifactId>
       </exclusion>
 </exclusions>

You can find a note in the platform-docker and share-docker projects about this. Example of adding an amp based dependency, note the exclusions part.

               <dependency>
			<groupId>de.fmaul</groupId>
			<artifactId>javascript-console-repo</artifactId>
			<type>amp</type>
			<version>0.6</version>
			<exclusions>
				<exclusion>
					<groupId>*</groupId>
					<artifactId>*</artifactId>
				</exclusion>
			</exclusions>
             </dependency>

Ahh, so obvious, the PARENT pom. I was just building the alfresco-platform. But you are saying that if I add the exclusions to say alfresco-share, It would create an AMP?

Uncommenting the "maven-assembly-plugin" would start creating amps along with jars as well. Even if you build alfresco-platform sub-project, and if "maven-assembly-plugin" is enabled, you would get jar and amp both for that sub-project.

Hi @mangar

Glad you got it resolved & thanks for accepting the solution - that's helpful to other users.

Kind regards,

Hi, Abhinav!
1) Can you explain please why it is required to add <exclusions>?

<exclusions>
       <exclusion>
         <groupId>*</groupId>
         <artifactId>*</artifactId>
       </exclusion>
 </exclusions>

What is it required for?
It is really not obvious - I tried with and without and did not notice any difference.

2) Also pom contains comment:

If using amp extensions only, add <includeTypes>amp</includeTypes> to the "collect-extensions" execution below.

Can you explain also this - in what cases it is used?

Thanks in advance.
