ClassNotFoundException

Hi I've been trying to use your tool but I ran into this error when using $ java -jar Postman2Jmx.jar my_postman_collection.json my_jmx_file.jmx

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
        at com.loadium.postman2jmx.app.Postman2Jmx.<clinit>(Postman2Jmx.java:15)

        ... 1 more

with java 14 and 11, and Maven 3.8.3, on windows and wsl

Any idea what is happening ? Thanks !

I was able to build a working jar by making it a fat jar, this way it works 👍

我在进行json文件转jmx文件时报错了。这是我输入的命令行。“java -jar Postman2Jmx.jar /f/XXXX.postman_collection.json postman_file.jmx”

以下为报错信息
“Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

I created an uber/fat jar using following maven plugin "maven-shade-plugin"

<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>3.2.4</version> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <mainClass>com.loadium.postman2jmx.app.Postman2Jmx</mainClass> </transformer> </transformers> </configuration> </execution> </executions> </plugin>

   But it appears the following error while executing the jar file.
   
   `Error: A JNI error has occurred, please check your installation and try again
