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?

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

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 .

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

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,

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
