Fresh setup a local AEM development environment not working: No marketplace entries found to handle maven-clean-plugin:3.0.0:clean and "] Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:3.0.0-M3:enforce" in eclipse

[nutmix]

I have followed this guide to the letter on a clean windows pc: https://experienceleague.adobe.com/docs/experience-manager-learn/foundation/development/set-up-a-loc... 

So have a running author jar, mvn and java installed, eclipse EE setup with the sling and aem "dev tools"

The final step of the instructions is to import the "completed wknd" tutorial. However, the wknd tutorial requires the dev env setup, and dev env setup requires the tutorial.

As a way out of this, I downloaded the source zip from https://github.com/adobe/aem-guides-wknd/releases/tag/aem-guides-wknd-0.0.6

Then I did "file->import->existing maven projects" on the source dir.

But it wont import.

It pops up the error "No marketplace entries found to handle maven-clean-plugin:3.0.0:clean in Eclipse.  Please see Help for more information"

The instructions are also missing two critical steps: 

1. when you do a fresh install of eclipse, you have to add a jdk under window->preferences->installed JREs
2. When you create a new run configuration, you have to go to the JRE tab and change it from the default "alternate JRE" to "workspace default jdk".

When I try to run the "install WKND pacakge" configuraiton, I get 3 errors:

1. The requested profile "autoinstallPackage" could not be activated because it does not exist.
2. No marketplace entries found to handle maven-clean-plugin:3.0.0:clean
3. Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:3.0.0-M3:enforce (enforce-checksum-of-immutable-files) on project aem-guides-wknd.dispatcher.cloud: Some Enforcer rules have failed.

Here is an example output with the errors:

[WARNING] Rule 9: org.apache.maven.plugins.enforcer.RequireFileChecksum failed with message:

i notice it says "displatcher.cloud".  Why cloud? I am running a local install, nothing to do with cloud?

Hi @nutmix 

Import the main folder(aem-guides-wknd-aem-guides-wknd-0.0.6) which has parent pom.xml. 

Update your Compiler plugin as below

<!-- Maven Compiler Plugin -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <verbose>true</verbose>
    </configuration>
</plugin>

[nutmix]

Thanks for the reply. I already imported this directory and eclipse picks up all the pom files, and this is what gives that missing clean error. Which file shall I edit to set the compiler??

[Anudeep_Garnepudi]

Update the Maven Compiler Plugin in parent pom.xml as above and try to build

[nutmix]

interestingly, this is whats in there now:

            <!-- Maven Compiler Plugin -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <release>1.8</release>
                </configuration>
            </plugin>

                <!-- Maven Compiler Plugin -->
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.8.1</version>
                </plugin>

I do have java 11 installed, but I dont know how maven knows where to get it from, as I had to switch from java 11 to java 8 to get the publisher to work.

you are suggesting I add "source" and "target", but currently it only has "release".  Also, the artifact is in the pom twice.

[Anudeep_Garnepudi]

The WKND project was built on Java 11, as you are using Java 8 remove the release tag and add above configuration.

[Anudeep_Garnepudi]

Update this

<!-- Maven Compiler Plugin -->

<plugin>

    <groupId>org.apache.maven.plugins</groupId>

    <artifactId>maven-compiler-plugin</artifactId>

    <configuration>

        <release>11</release>

    </configuration>

</plugin>

with

<!-- Maven Compiler Plugin -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <verbose>true</verbose>
    </configuration>
</plugin>

[nutmix]

ok, tried the updated pom with 1.8, same error. So I switched back to java 11 on the command line, JAVA_HOME, eclipse defautl JDK and the JDK for the run config.

Now it gets further but fails with this:

[WARNING] The requested profile "autoinstallPackage" could not be activated because it does not exist.
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:3.0.0-M3:enforce (enforce-checksum-of-immutable-files) on project aem-guides-wknd.dispatcher.cloud: Some Enforcer rules have failed. Look above for specific messages explaining why the rule failed. -> [Help 1]

[Anudeep_Garnepudi]

I am able to build successfully with Java 8

[nutmix]

if you can build, and I cant, it could be anything. I may have been given a bad or wrong quickstart.jar, I may have a version of java which it doesnt work for, I my require an undocumented setting in eclipse, it may be different versions of the wknd project (I had no idea where to get it from so took a complete guess). I followed the tutorial to the letter, although it has several missing steps and critical missing information.

[nutmix]

Anudeep, could you tell me exactly where you got your copy of wknd from? Exactly which dir/files? I seem to have some cloud version, and I dont have the ckould SDK, only local jar.

Could you also confirm if you are running the clould SDK, or the non cloud sdk? I only have the non cloud.

[Anudeep_Garnepudi]

Try building the project from command prompt, your eclipse build in Maven and Java versions might be different. Building from command prompt could solve your issue.

You can just go to parent pom.xml, and comment out the "dispatcher.cloud" module. Next, mvn clean install again. Since you do not have the correct profile, head into ui.apps/target/.*.zip, and upload it manually into AEM using the package manager. Your build logs looks fine, except for the dispatcher.cloud maven module.
