I'm trying to run a program inside of an .jar file. To create the .jar file inside of te projects target folder I used the command mvn clean package spring-boot:repackage.
After I start the program with java -jar middleware-0.0.1-SNAPSHOT.jar an error message appears.
The entire error message:

The resource the program was not able to find is located inside another project. I referenced the remote project inside the Java Build Path and inside my pom.xml.

Inside of my IDE (Eclipse) everything is working fine, but the .jar file throws the error above.
I know many other people have this problem, but most of them tried to load a file (.xml for example) and I'm trying to implement an interface. I don't know how much this is different.
I would really appreciate if you could help me out. Thanks in advance-
CodePudding user response：
check if your system scoped dependency is included in the jar! You can unpack the jar with any zip tool.
If you want to include it, check the includeSystemScope option of the spring-boot:repackage goal: https://docs.spring.io/spring-boot/docs/1.4.1.RELEASE/maven-plugin/repackage-mojo.html#includeSystemScope
Just an example, so you can see how to add the option. It's added in the pom.xml file of your project.
[...]
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>full.qualified.MainClass</mainClass>
<layout>ZIP</layout>
<classifier>exec</classifier>
<includeSystemScope>true</includeSystemScope>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
[...]
If you don't want to include it you have to add the jar to your classpath while executing the jar:
(Unix style)
java -cp "middleware-0.0.1-SNAPSHOT.jar:C:\Users\mfi\Downloads\LaunchableJar\remote.jar" -Dloader.main=<YOUR_MAINCLASS_HERE> org.springframework.boot.loader.PropertiesLauncher "$@"
