I think I don(t put the library (build.gradle.kts) in the right file I have put my java class in src/protocol/http/src/main/java/org/apache/jmeter/protocol/http/gui/action/ParseHARAction.java and modify src/protocol/http/build.gradle.kts For code I have commit it in https://github.com/ra0077/jmeter/tree/Add_HAR_convertor Le jeu. 8 juin 2023 à 22:28, Vladimir Sitnikov <sitnikov.vladi...@gmail.com> a écrit : > >Any idea to solve this problem? > > It is hard to understand the reason for the failure without looking into > the code. > It would be great if you could file a draft pull request with your changes. > > Here's how you could add har-reader module into JMeter: > https://github.com/apache/jmeter/pull/5976 > > "import de.sstoehr.harreader.HarReader" works for me > > Vladimir >
