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

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?

Solution 1:^[1]

OK to resolve the issue, in my maven package build;

1) Invoked ANT to unzip the released template SPRING-BOOT-app.jar
2) Unzip and repackage additional shaded artefact from the project
3) Copy repackaged artefact under BOOT-INF/lib
4) Repackage SPRING-BOOT-app.jar

My pom now have the following additional step;

pom.xml

    <plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <executions>
        <execution>
            <id>repackage-app</id>

            <goals>
                <goal>run</goal>
            </goals>
            <configuration>
                <target name="repack-app">
                    <property name="workDirectory" value="${project.build.directory}/app-repack" />
                    <property name="sourceArtifact" value="${project.build.directory}/SPRING-BOOT-app.jar" />
                    <property name="appendWith" value="${project.build.directory}/${project.artifactId}-${project.version}.jar" /> 
                    <ant antfile="${packager.utilities.directory}/build.xml"> 
                        <target name="append-and-repack-spring-boot-artiafact" />
                    </ant>
                </target>
            </configuration>
        </execution>
    </executions>
</plugin>

NOTE: Do NOT USE 7Zip/Winrar or any other compression tools to open the Spring Boot App which you are planning to deploy. It would update the compression offset (or something) and app would fail. Just don't touch the artefact, take a copy and inspect!

Solution 2:^[2]

Fix for us, same failure message, was to use just the spring-boot-maven-plugin (which creates a runnable jar for you) instead of using the shade plugin and running it from that jar.

Solution 3:^[3]

Add this in plugin configuration while building the jar.

           <archiverConfig>
                <compress>false</compress>
            </archiverConfig>
