Doesn't work with springboot project

[noxymon]

i tried this maven plugin using spring pet client project here :

https://github.com/spring-projects/spring-petclinic

using this config :

<plugin>
   <groupId>com.iluwatar.urm</groupId>
   <artifactId>urm-maven-plugin</artifactId>
   <version>2.0.0</version>
   <configuration>
      <packages>
         <param>org.springframework.samples.petclinic.owner</param>
      </packages>
      <includeMainDirectory>true</includeMainDirectory>
   </configuration>
   <executions>
      <execution>
         <phase>process-classes</phase>
         <goals>
            <goal>map</goal>
         </goals>
      </execution>
   </executions>
</plugin>

uml output is only

@startuml
@enduml

run it with java 11 openjdk. is there any missing config of mine ?

Same problem here. Using both the maven plugin and the CLI it just doesn't produce anything at all.

doesn't seem to work with spring-boot project. Tried both maven plugin and cli

Sam here. Just tried the CLI and only received:

@startuml
@enduml

Was going to try the maven plugin but then found this issue.

OK, I know why this happens.

Springboot uses spring-boot-maven-plugin that does some repackaging, changing the default folder structure of the jar (puting the "generated jar" inside a BOOT-INF/classes/ folder).

We can "fix it" with two (or more) ways, the first is very simple, on the target folder there is a .original file, we could use it.

Another solution is using another plugin to generate the -jar-with-dependencies.jar version and use it:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
            <configuration>
                <finalName>${project.name}-${project.version}</finalName>
                <archive>
                    <manifest>
                        <mainClass>
                            ${main.class}
                        </mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
        </execution>
    </executions>
</plugin>

I have the same problem with a SpringBoot project! Im using Java 18 and SpringBoot version 2.7.0.

The plugin only generates:

@startuml
@enduml

or:

digraph domain {
  edge [ fontsize = 11 ];
  node [ shape=record ];
}

@crossworth When I use the CLI, either with .original or -jar-with-dependencies.jar, I get the error:

java.lang.ClassNotFoundException: com.iluwatar.urm.DomainMapperCli

For running I use the following command:

java -cp SNS-1.5.2-jar-with-dependencies.jar:urm-core-2.0.0.jar com.iluwatar.urm.DomainMapperCli -p ch.bztf.m226blb1.Database.Entities

Is there any way to run the plugin in Maven directly / configure that the .original should be used??? @iluwatar

Same issue facing @iluwatar
Can you please help us

[klingen-m]

@kravitej9 @21r8390 you are missing the urm-core-2.0.0.jar in the classpath
try this:
java -cp .\xyz-0.0.1-jar-with-dependencies.jar -cp .\urm-core-2.0.0.jar com.iluwatar.urm.DomainMapperCli -p my.package

anyway it still doesn't create diagrams from spring projects no matter if jar-with-dependency .original or .war @iluwatar

[klingen-m]

Hey @iluwatar,
I implemented a solution, by creating my own classloader and add the files from within the jar manually at runtime and hand this classloader to the exisiting methods. Works like a charm...don't mind if you give me push access so i can upload the branch

in the mean time => https://github.com/klingen-m/uml-reverse-mapper/tree/feature/add-war-support
