  • Configure Eclipse 4.6.x with HCL Notes 12.0.1 FP1

    Once again I had to ask HCL development for setup instructions how to launch the HCL Notes Standard Client from an Eclipse IDE, this time for Notes 12.0.1 FP1.

    The instructions I had gotten earlier for Notes 10 have not changed much (I think there's one additional VM argument at the end of the list), but enough so that they did not work anymore.

    The document links to Eclipse Neon 4.6.3, but it's still working for me in later versions, I tried it with Eclipse 2020-09 (4.17.0, 64 bit).

    I used my local installation directory in the text below (C:\Program Files (x86)\HCL\Notes) and the plugin version for com.ibm.rcp.base in Notes 12.0.1 FP1.

    Of course these need to match your local environment.

    1. Download Eclipse Neon (4.6.3) or later from link below:


    2. Get HCL Notes 12.0.1 FP1

    I used the instructions with the 32 bit Notes Client so far.

    • Add => Standard VM =>

    Ensure that whenever you launch the Notes from Eclipse, there should be no other instance of Notes already running. If so, please close Notes and then launch from Eclipse to debug.
