Failed to get nested archive for entry BOOT-INF/lib for jar created with maven-shaded-plugin

[junejosheeraz]

I am using spring-boot-maven-plugin:2.1.0.RELEASE to package my main line application. This application has all common dependencies etc packaged

In a separate project, I am building a shaded jar using maven-shade-plugin:2.4.3 and injecting into my spring boot application under BOOT-INF/lib directory using org.codehaus.mojo:truezip-maven-plugin:1.1. Now when I start my spring-boot application I am getting following exception;

I tried to copy the jar inside BOOT-INF/lib directly taking maven-truezip-plugin out but still the same. Is there anyway I can solve this? or a workaround?

[wilkinsona]

As the error message says, jars in BOOT-INF/lib must be stored in the jar file uncompressed. I’m not familiar with the true zip plugin. Perhaps it has an option for controlling the compression of an entry when it adds it to a zip file? If you need any further guidance, please follow up on Stack Overflow or Gitter.
