used mvn package to build the jar. Once build the jar, trying to run the following command java -jar swagger-diff-1.2.2.jar --help

But getting error - no main manifest attribute, in swagger-diff-1.2.2.jar

Same story over here. Have not conclusion why this happens yet.

java -jar swagger-diff-1.2.2.jar -old /home/software/swagger-diff/swagger_v0p9.json -new /home/software/swagger-diff/swagger_v0.91.json -v 2.0 -output-mode html > diff_v0.9_v0.91.html

Leads to: put-mode html > diff_v0.9_v0.91.html no main manifest attribute, in swagger-diff-1.2.2.jar

The HTML-File is 0 Bytes long and therefore empty.

$ java -version openjdk version "11.0.10" 2021-01-19 OpenJDK Runtime Environment (build 11.0.10+9-Ubuntu-0ubuntu1.20.04) OpenJDK 64-Bit Server VM (build 11.0.10+9-Ubuntu-0ubuntu1.20.04, mixed mode, sharing)

Version 1.2.1 has the same result.

Tried the asset of https://github.com/Sayi/swagger-diff/releases (swagger-diff.jar 10.1 MB)

leads to a different result though:

put-mode html > diff_v0.9_v0.91.html Exception in thread "main" java.lang.RuntimeException: cannot read api-doc from spec. at com.deepoove.swagger.diff.SwaggerDiff.(SwaggerDiff.java:122) at com.deepoove.swagger.diff.SwaggerDiff.compare(SwaggerDiff.java:81) at com.deepoove.swagger.diff.SwaggerDiff.compareV2(SwaggerDiff.java:53) at com.deepoove.swagger.diff.cli.CLI.run(CLI.java:66) at com.deepoove.swagger.diff.cli.CLI.main(CLI.java:51)

Tried again with an older JAVA-Version:

java version "1.8.0_241" Java(TM) SE Runtime Environment (build 1.8.0_241-b07) Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)

"C:\Program Files\Java\jdk1.8.0_241\bin\java.exe" -jar swagger-diff-1.2.2.jar -old swagger_v0p9.json -new swagger_v0.91.json kein Hauptmanifestattribut, in swagger-diff-1.2.2.jar

Clone my fork repository and execute this command:

mvn package

Then you can use swagger-diff-1.2.2-jar-with-dependencies.jar to execute the command line tools.

It is enough to download: https://github.com/Sayi/swagger-diff/releases/download/v1.2.2/swagger-diff.jar It is executable and it works correctly.
