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

Description 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 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 ClassLoader bundle.  You can also check the bundle number in the  AEM Web Console and 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 Console and access that folder directly on the file system under crx-quickstart/launchpad/felix by going under same bundle.
