Learn how to force recompilation of Sling scripts JSP, Java, and Sightly in AEM 6.5.

Description

Environment

Adobe Experience Manager (AEM) 6.5

Issue/Symptoms

This article will show how to force recompilation of all Sling scripts like JSP, Java, and Sightly in AEM 6.5.

Resolution

Sometimes the JSP, HTL clientLibs, or classes will not get recompiled automatically in Adobe Experience Manager (AEM).  Strange UI issues can occur, and compilation errors may be seen in the logs. Now, we do not have libraries under the /var/clientlibs folder anymore. They are in the file system.

 1. Recompile via AEM Web Console:

  • For clientlibs access [ 1] , click Invalidate Caches, then click Rebuild Libraries.
  • For classes, JSPs and Sightly cache, go to [ 2] and click Clear ClassLoader on the top right side.

 2. Recompile via the file system

For classes, JSPs and Sightly cache:

  • Search the server where the AEM instance is deployed. From home folder run command: find launchpad/felix -path "*/bundle*/data/classes" -type d
  • Delete the classes folder.

Note: Classes and Sightly cache are stored in the Apache Sling Commons FileSystem ClassLoaderbundle.  You can also check the bundle number in the AEM Web Consoleand access that folder directly on the file system under crx-quickstart/launchpad/felix.

For ClientLibraries

  • Search in the server where the AEM instance is deployed. From home folder run command: find launchpad/felix -path "*/bundle*/data/outputcache" -type d.
  • Delete outputcache folder.

*Note:*Clientlibs is now stored in the Adobe Granite UI Clientlibs.  You can also check the bundle number in the AEM Web Consoleand access that folder directly on the file system under crx-quickstart/launchpad/felix by going under same bundle.
