The problem you're facing during the compilation of your AEM (Adobe Experience Manager) project is related to the "mvn clean install -PautoInstallSinglePackage" command. When executing this command, you're encountering an error in the "target" folder within "generated-sources/htl". It appears that the build process is unable to delete these files during compilation.

Please try deleting the target folder from ui.apps module manually and try the build again. Some times the clean commands doesn't execute as expected. Maybe due to file type or folder permissions.

@Johnhenao10 Most likely there is another process holding a lock on this folder. Most of the times (at least for me) the culprit is the IDE (eclipse, intelliJ).
Try closing the IDE and then run the build.
Hi @Johnhenao10
Try mvn clean alone or deleting the file by following the folder structure and run mvn clean install.
Hello @Johnhenao10
1. Please assure target folder is not accessed in any command line or other tool
2. Restart IDE
3. Sometimes, we might still not be able to resolve. So, restart system
@Johnhenao10 All the suggestions provided by Advisors are correct. Basically this happens when the mvn is unable to delete the target folder while you run the mvn command.
Below are the solutions
1. If you run the "cmd" with admin privelages
2.if you can run mvn clean before you run mvn install that also helps.
3. If another program is using the target folder please close it and rerun it once again.
