Solution

Depending on the exit code you got, do the follwoing:

I. Check that your java home is configured correctly to installed java, which version is needed for your system version.
(You have to ensure correct OS path to javac.exe in OS environment, where the whole JDK (not only jre) is installed)

II. This exit code means that the java files which should be compiled are not found. Check if the java files exist at the specified location.

III. Increase the memory of the compiler(apply the related SAP Note below)
Proceed as follows:
1. Start the Config Tool in <J2EE_HOME>/configtool directory
2. In the the tree in the left pane, navigate to
cluster-data -> <Tempate Name> -> services -> classpath_resolver
cluster-data -> <Tempate Name> -> Instance IDXXXXXX -> services -> classpath_resolver
3. In the right pane, choose on the key "javac.Xmx"
4. In the "Custom Value" text field, write a higher value. For example: 512
5. Choose "Set Custom Value".
6. In the "File" menu, choose "Apply Changes" and confirm all windows popping up.
7. Restart AS Java.
8. Restart the deployment process (or failed scenario)

IV. This means that the OS cannot find enough memory to execute a compilation process. You can increase you OS memory by increasing the swap file.
