[Wrapper-user] Tanuki-Wrapper doesn't work with Spring boot 2 executable jar

[Pravin S. K. <pka...@tr...>]

Dear Tanuki Wrapper Support Team,


We were using Tanuki Wrapper(version 3.5.25) with Spring boot 1 earlier without any issue.

With Spring Boot 2, I am getting below error.

STATUS | wrapper  | Launching a JVM...

INFO   | jvm 4    | Error: Could not find or load main class com.mycompany.project.App

ERROR  | wrapper  | JVM exited while loading the application.


Main class in wrapper conf file -

wrapper.java.mainclass=com.mycompany.project.App

Because of Spring boot 2, my application jar structure has changed and different from previous structure which causes above error.

Spring boot 2 jar structure below(Throwing above error)-

example.war
 |
 +-META-INF
 |  +-MANIFEST.MF
 +-org
 |  +-springframework
 |     +-boot
 |        +-loader
 |           +-<spring boot loader classes>
 +-BOOT-INF
    +-classes
    |  +-com
    |     +-mycompany
    |        +-project
    |           +-App.class
    +-lib
    |  +-dependency1.jar
    |  +-dependency2.jar


Spring boot 1 jar structure (Working well with Tanuki wrapper 3.5.25) below:

example.war
 |
 +-META-INF
 |  +-MANIFEST.MF
 +-org
 |  +-springframework
 |     +-boot
 |        +-loader
 |           +-<spring boot loader classes>
 +-com
 |   +-mycompany
 |       +-project
 |           +-App.class
 +-lib
   +-dependency1.jar
   +-dependency2.jar


Could you please provide your inputs to resolve the issue?


Thanks,

Pravin
