Error creating shaded jar: Invalid signature file digest for Manifest main attributes

Problem :


 Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes
Solution :

 You need to add the following to pom.xml:
search for your maven-shade-plugin under <plugin> </plugin>
POM.xml

        <configuration>
          <filters>
            <filter>
              <artifact>*:*</artifact>
              <excludes>
                <exclude>META-INF/*.SF</exclude>
                <exclude>META-INF/*.DSA</exclude>
                <exclude>META-INF/*.RSA</exclude>
              </excludes>
            </filter>
          </filters>
        </configuration>

The above configuration filters all files in META-INF ending with .SF, .DSA, and .RSA for all artifacts (*:*) when creating uber-jar file.

 The reason java.lang.SecurityException is raised is because some dependency jar files are signed jar files.  A jar file is signed by using jarsigner, which creates 2 additional files and places them in META-INF:
a signature file, with a .SF extension, and
a signature block file, with a .DSA, .RSA, or .EC extension.
Since the uber-jar file is created, the signatures and integrity of signed JAR files are no longer valid.  When the uber-jar file is executed, java.lang.SecurityException is thrown.

java: You aren't using a compiler supported by lombok, so lombok will not work and has been disabled.

By
  In order to make projects compile with the existing builds of Lombok processor, as a workaround you can use the flag -Djps.track.ap.dependencies=false which should be added to File | Settings | Build, Execution, Deployment | Compiler | Build process VM options field. This will disable collection of dependencies specified by an annotation processor when Filer methods are called

Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.2.3.RELEASE:repackage failed: Unable to find main class

By
Solutions:  Solution 1 : You needed to change the packaging parameter to jar from pom. Also, the repositories , pluginRepositories , the maven-compiler-plugin and the spring-boot-maven-plugin's version and executions weren't needed. Solution 2:  Try mvn install and see if it works Solution 3: Preview: <properties> <!-- The main class to start by executing java -jar --> <start-class> com.mycorp.starter.HelloWorldApplication </start-class> </properties> Solution 4: Enable the main() method in your Application.java. Configure spring-boot-maven-plugin to specify the class with the main class (Spring should find it anyway if you have one, but good to be explicit): Preview: <plugin> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-maven-plugin </artifactId> <version> ${spring-boot-version} </version>...
