It says:
Specify each library as a <dependency> with a <groupId> and a <artifactId> and they will be unpacked at runtime in $TMPDIR/spring-boot-libs.
The name of the unpack folder now includes the name of the archive from which they're being unpacked and a UUID:
String fileName = new File(this.jarFile.getName()).getName();
File unpackFolder = new File(parent,
fileName + "-spring-boot-libs-" + UUID.randomUUID());
