AEM 6.1 java 1.8 compatibility issue

Hi,

we are trying to upgrade our project to AEM 6.1 and JDK 1.8 version . 

 

we are trying to modify the pom.xml files of my project. 

we used  the following combinations :

 

<plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.1</version>
                    <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
                </plugin>

<plugin>
                    <groupId>org.apache.felix</groupId>
                    <artifactId>maven-scr-plugin</artifactId>
                    <version>1.21.0</version>
                    <extensions>true</extensions>
                     <configuration>
                    <sourceExcludes>com/sapient/archive/*.java</sourceExcludes>
                </configuration>               
                    <executions>
                        <execution>
                            <id>generate-scr-scrdescriptor</id>
                            <goals>
                                <goal>scr</goal>
                            </goals>
                            
                        </execution>
                    </executions>
                </plugin>

 

 

<dependency>
            <groupId>org.apache.felix</groupId>
            <artifactId>org.apache.felix.scr.annotations</artifactId>
            <version>1.9.6</version>
            <scope>provided</scope>
        </dependency>

 

if we use the following combination in parent and as well and child we are getting the following error: 

 

[ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.21.0:scr (generate-scr-scrdescriptor) on project aem.foundation: SCR Descriptor parsing had failures (see log) -> [Help 1]

 

if we use the above combination only in parent, build got the success, but generated jar file is not creating OSGI-INF folder . 

 

 

can anyone please provide the sample pom.xml file which will both compatible with 1.7 and 1.8 . 

 

 

 

Thanks, 

Lakshmi Raghava Reddy M.

There seems to be some details on this issue online, looks like your java code may need to be updated. What version of AEM are you migrating from?

Hi,

Looks like the maven SCR plugin fails to parse the SCR annotations; can you run maven on debug (-X) and post the relevant exception? Please don't post the complete output then :)

Kind regards,
Jörg

Hi

Wanted to share my experience and learning with the group. I have faced same issues with maven-compiler and scr annotations with JDK 1.8 and AEM 6.1. I eventually found that its a maven compiler and related dependencies' compatibility to JDK 1.8 issue and resolved with following changes in my reactor project's POM.xml. Please note that:

  1. Earlier Environment - JDK 1.7, Maven 3.2.2 and AEM 6.0 SP1
  2. New Environment - JDK 1.8...73 (the latest at the moment), Maven 3.3.3 and AEM 6.1 SP1

Changes:

CHANGE-1: Under the tag <build><pluginManagement>

<!-- commented due to AEM 6.1 JDK 1.8 issue
<plugin>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.0</version>
   <configuration>
      <source>1.6</source>
      <target>1.6</target>
      <encoding>utf-8</encoding>
   </configuration>
</plugin>
-->

<!-- Added due to AEM 6.1 JDK 1.8 issue -->
<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.1</version>
   <inherited>true</inherited>
   <configuration>
      <source>1.8</source>
      <target>1.8</target>
   </configuration>
</plugin>

Change-2: Under the tag <build><pluginManagement>

<!-- Added due to AEM 6.1 JDK 1.8 Issue -->
<plugin>
   <groupId>org.apache.felix</groupId>
   <artifactId>maven-scr-plugin</artifactId>
   <version>1.17.0</version>
</plugin>

<!-- commented due to AEM 6.1 JDK 1.8 Issue
<plugin>
   <groupId>org.apache.felix</groupId>
   <artifactId>maven-scr-plugin</artifactId>
   <version>1.8.0</version>
</plugin>
-->

Change 3: Under the tag <dependencyManagement><dependencies>

<!-- Added due to JDK 1.8 AEM 6.1 issue -->
<dependency>
   <groupId>org.apache.felix</groupId>
   <artifactId>org.apache.felix.scr.annotations</artifactId>
   <version>1.9.8</version>
</dependency>

<!-- commented due to JDK 1.8 AEM 6.1 issue
<dependency>
   <groupId>org.apache.felix</groupId>
   <artifactId>org.apache.felix.scr.annotations</artifactId>
   <version>1.7.0</version>
</dependency>
-->

It solved my AEM 6.1 JDK 1.8 issue related to scr annotation issue as described in this POST originally.

 

Cheers
