AEM 6.1 java 1.8 compatibility issue

[lakshmi_raghava]

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.

can any one help

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 Jorg,

Following is the error that i am getting once i ran the build with debug mode:

Please provide the answer if you know.

Hm,

what version of Java are you using to run Maven? I haven't tried it with Java8 yet. Please check the URLs Opkar already posted.

kind regards,
Jörg

[Opkar_Gill · Accepted solution]

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?

https://issues.apache.org/jira/browse/FELIX-4586

Hi Jorg,

In my local, i am using maven version -3.0.4 and in pom.xml file we are using maven-version as 3.1 and maven-scr-plugin version is 1.20. 

As per the Opkar URLs, we modified code by adding volatile to the reference. My build got success,  i deployed the jar files to console  but some of the components were in unsatisfied mode and when i tried to activate them, those components were disappearing from component console.  

Did you face this issue as well, can you please help us to resolve this issue. 

please let me know, if you need more details. 

Thanks,

Lakshmi Raghava Reddy M.

i am migrating AEM 6.0 to AEM 6.1 version. 

[Opkar_Gill]

When you deploy your package to AEM, tail the error.log file and see if any errors are thrown when your bundle is started.

Regards,

Opkar

Hi Opkar,

Yes there are some errors, it's related my project. But with out having project code deployment, following out of box components are in unsatisfied  mode. I am using Java 8 in my local.

Please let me know, whether we can ignore those issues or not?

Hi, I am also facing the similar kind of problem. Please let me know if there is any fix

[lakshmi_raghava]

Yes, we figure out the issue and issue and issue is with the code that we modified for the deprecated API. With out code changes of Deprecated API, everything is working fine with java 8 .

[Jörg_Hoh]

Unsatiesfied components are not an issue in the first place. A number of them will only get active if you provide proper configuration. This depends on the component.

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>
-->

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