作为Maven插件运行的Spring Boot可以运行，但是作为打包的应用程序失败

Question

I'm trying to run a Spring Boot app that uses Jersey. When running with 'mvn spring-boot:run' it starts up and works fine.

However, when I run as a packaged application ('java -jar ...') I get a FileNotFoundException that looks like:

Caused by: java.io.FileNotFoundException: /.../appsensor-ws-rest-server-boot/target/appsensor-ws-rest-server-boot-0.0.1-SNAPSHOT.jar!/lib/appsensor-ws-rest-server-2.2.0-SNAPSHOT.jar (No such file or directory)

When I look at the generated jar via

jar -tf target/appsensor-ws-rest-server-boot-0.0.1-SNAPSHOT.jar | grep ws-rest-server

, I get:

lib/appsensor-ws-rest-server-2.2.0-SNAPSHOT.jar

So the file appears to be there. Thoughts?

Actually found an answer after a bit more looking, and leaving this for others who might have the same problem.

This resource had the right answer: http://midgetontoes.com/blog/2015/04/13/filenotfoundexception-when-using-jersey-with-spring-boot

Essentially, you have to modify the configuration of the spring-boot-maven-plugin in some cases and add the requiresUnpack element for any dependent jars that require unpacking.
