使用java.jar以tools.jar作为依赖项运行spring boot

Question

I am trying to run a springboot app that needs tools.jar as a dependency, I runned "mvn package spring-boot:run" and everything goes ok, but after packaging with "mvn package spring-boot:repackage" and running with java -jar the generated boot.jar the throws the following error

java -jar "site-0.1.0-spring-boot.jar"

JAVA_HOME is pointing to JDK as it should, and this is my pom

Any Idea of how should I run it without mvn? what am I doing bad?

Answer 1

System scope dependencies are not added in the repackaged jar (eg 'fat' jar). That is why your app works fine in development (with the "local" classpath) and does not when started as a separate package.

The upcoming Spring Boot 1.4.0.RC1 release will support this feature : you'll be able to set includeSystemScope in your Maven plugin configuration and any system scoped dependencies will be included. Note that repackaging tools.jar is probably a smell, see this question
