Java springboot packaging error

[Bestbbb]

OR-TOOLS runs in the development environment normally,but when I package or install it in the springboot jar,it will show the error:
java.nio.file.NoSuchFileException: /BOOT-INF/lib/ortools-win32-x86-64-9.4.1874.jar!/ortools-win32-x86-64

I try all the methods metioned before,but it cannot work

This is because Spring Boot does not shade the included jars the same way other builds do, see:

https://docs.spring.io/spring-boot/docs/current/reference/html/executable-jar.html#appendix.executable-jar.nested-jars

There is an issue that describes this with several solutions.

Attached what I have used which is different what the issues show as solutions

SpringBootOrToolsNativeLoader.zip

Reuploaded with the typo fixed incase anyone else stumbles upon this thread.

@Bestbbb can you please share if the steps mentioned over here are correct to switch from spring-boot-maven-plugin to maven-shade plugin?

If not can you please share the same

I shared it,it is a little different.

I try a solution,I use the maven-shade plugin instead of spring-boot-maven-plugin,and finally it works.

for me as well the solution provided in SpringBootOrToolsNativeLoader only with maven-shaded-plugin and not with spring-boot-maven-plugin
@henszey just checking if the solution also works with spring-boot-maven-plugin?

I use this method, but this error occurred：
java.nio.file.ProviderNotFoundException: Provider not found

The best solution for me was described in this ticket by @C-Otto https://github.com/magneticflux-/ortools-java/issues/5#issuecomment-1075407198 . Just add this to your build file:

bootJar {
    requiresUnpack '**/ortools-darwin*.jar', '**/ortools-win32*.jar', '**/ortools-linux*.jar'
}

I used this solution in maven using the spring-boot-maven-plugin

<build>
  <plugins>
    <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
      <version>${project.parent.version}</version>
      <configuration>
        <requiresUnpack>
            <dependency>
              <groupId>com.google.ortools</groupId>
              <artifactId>ortools-java</artifactId>
            </dependency>
            <dependency>
              <groupId>com.google.ortools</groupId>
              <artifactId>ortools-linux-x86-64</artifactId>
            </dependency>
            <dependency>

    </plugin

</build>
