Replace the default package configuration files to customize the package properties. For example, include a thumbnail image to distinguish the package in Package Manager and Package Share.
In the package, FileVault-specific files are located in the /META-INF/vault folder. The source files can be located anywhere in your file system. In the POM file, define build resources to copy the source files to the target/vault-work/META-INF for inclusion in the package.
The following POM code adds the files in the META-INF folder of the project source to the package:
<!-- vault META-INF resources (thumbnail etc.) -->
The following POM code adds only a thumbnail image to the package. The thumbnail image must be named thumbnail.png, and must be located in the META-INF/vault/definition folder of the package. In this example, the source file is located in the /src/main/content/META-INF/vault/definition folder of the project:
<!-- thumbnail only -->
