I have already did what the BlazeMeter guide said and made a scenario the Xmpp server is connecting but when I reach the Login I get the exception No response. I have already searched and saw what people said and did and so I tried to build the plugin project with maven and got the jmeter-xmpp-plugin 1.5.1 jar file, then I replaced the old jar (which I downloaded using the plugin manager in jmeter) in the "lib/ext" folder with it, but another exception got caught which is :

"java.lang.IncompatibleClassChangeError: Found class org.jivesoftware.smack.XMPPConnection, but interface was expected at com.blazemeter.jmeter.xmpp.JMeterXMPPConnection.setUpConnection(JMeterXMPPConnection.java:91) ~[jmeter-plugins-xmpp-1.5.1.jar:?] at com.blazemeter.jmeter.xmpp.JMeterXMPPConnection.getConnection(JMeterXMPPConnection.java:83) ~[jmeter-plugins-xmpp-1.5.1.jar:?] at com.blazemeter.jmeter.xmpp.JMeterXMPPSampler.getXMPPConnection(JMeterXMPPSampler.java:81) ~[jmeter-plugins-xmpp-1.5.1.jar:?] at com.blazemeter.jmeter.xmpp.JMeterXMPPSampler.sample(JMeterXMPPSampler.java:38) ~[jmeter-plugins-xmpp-1.5.1.jar:?] at org.apache.jmeter.threads.JMeterThread.doSampling(JMeterThread.java:651) ~[ApacheJMeter_core.jar:5.6.2] at org.apache.jmeter.threads.JMeterThread.executeSamplePackage(JMeterThread.java:570) ~[ApacheJMeter_core.jar:5.6.2] at org.apache.jmeter.threads.JMeterThread.processSampler(JMeterThread.java:501) ~[ApacheJMeter_core.jar:5.6.2] at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:268) ~[ApacheJMeter_core.jar:5.6.2] at java.lang.Thread.run(Thread.java:829) [?:?] "

I do not know if any steps were missed or mistakes were made but I need some guidance through or steps to follow.

I want to State that -> my real problem is the login No Response Exception that is :

org.jivesoftware.smack.SmackException$NoResponseException: null at org.jivesoftware.smack.PacketCollector.nextResultOrThrow(PacketCollector.java:191) ~[smack-core-4.0.7.jar:4.0.7] at org.jivesoftware.smack.PacketCollector.nextResultOrThrow(PacketCollector.java:175) ~[smack-core-4.0.7.jar:4.0.7] at org.jivesoftware.smack.XMPPConnection.bindResourceAndEstablishSession(XMPPConnection.java:535) ~[smack-core-4.0.7.jar:4.0.7] at org.jivesoftware.smack.tcp.XMPPTCPConnection.login(XMPPTCPConnection.java:260) ~[smack-tcp-4.0.7.jar:4.0.7] at com.blazemeter.jmeter.xmpp.actions.Login.perform(Login.java:51) ~[jmeter-plugins-xmpp-1.5.1.jar:?] at com.blazemeter.jmeter.xmpp.JMeterXMPPSampler.sample(JMeterXMPPSampler.java:57) [jmeter-plugins-xmpp-1.5.1.jar:?] at org.apache.jmeter.threads.JMeterThread.doSampling(JMeterThread.java:651) [ApacheJMeter_core.jar:5.6.2] at org.apache.jmeter.threads.JMeterThread.executeSamplePackage(JMeterThread.java:570) [ApacheJMeter_core.jar:5.6.2] at org.apache.jmeter.threads.JMeterThread.processSampler(JMeterThread.java:501) [ApacheJMeter_core.jar:5.6.2] at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:268) [ApacheJMeter_core.jar:5.6.2] at java.lang.Thread.run(Thread.java:829) [?:?]

Building a single .jar containing the plugin only might be not the best idea as you may create yourself a Jar Hell due to API mismatch between the plugin and its dependencies.

So I would recommend

  1. Installing clean latest version of JMeter which is JMeter 5.6.2 as of now

  2. Installing clean latest version of XMPP Plugin which is 1.5.1 as of now using JMeter Plugins Manager

    enter image description here

    and at least this IncompatibleClassChangeError issue will go away.
