Error when connecting to Modbus RTU and connecting with jSerialComm

[kk99999]

I am creating Modbus RTU and trying to connect using jSerialComm. I am getting below error though the method exists in jSerialComm.

java.lang.NoSuchMethodError: 'void com.fazecast.jSerialComm.SerialPort.setComPortParameters(int, int, int, int)'

I verified that there is only one version of jSerialComm(2.10.4) library. Below is the code to connect. SerialParameters serialParameters = new SerialParameters("COM1", SerialPort.BaudRate.BAUD_RATE_9600, 8, 1, SerialPort.Parity.EVEN); SerialUtils.setSerialPortFactoryJSerialComm(); ModbusMasterFactory.createModbusMasterRTU().connect();

Any thoughts?

I am seeing this issue with jSerialComm versions > 2.6.0. If using 2.6.0 and earlier version I don't see this issue. Any chance this can be verified and may be resolved? jLibModbus version is 1.2.9.7.

Just testet with JSerialComm v2.10.4. Everything is OK.

@kochedykov Hi, for me this error still persists. I am using jLibModbus v1.2.9.9 and jSerialComm v2.10.4.

Yes, here is the error log:

Did you add the jSerialComm path to classpath?

Yes, here is the error log:

Yes, it is added to the classpath, library is also found inside the packed JAR.

Hi, just a note. This issue seems to be resolved when updating jSerialComm to the latest version inside jlibmodbus. And also jlibmodbus version 1.2.9.11 from Maven Central seems to resolve this issue.
