Java package not found when compiling code

I am a JAVA Novice, and I am trying to run the NASA DAA-Displays project found here: daa-display/NASA on my local computer. However, when I trying to run one of the makefile, I am getting an error. Prior to posting this question, I have gone through the files in the project to the best of my ability. I have followed the instructions and have the required packages to go with this project. When I first cloned the project, I followed all the instructions that could be found in the readme.md files. However, upon following these instructions I was met with some errors. After some debugging and working my way through these errors, I have reached this point.

Here are the first errors I got when I ran the make command on the cloned folder as is (PLEASE NOTE: These errors do not exist anymore, they are just to provide reference to make sure that I have not messed up anything in the core):

After this, I fixed the path errors which were redirecting the code to path that do not exist. Once this was done, I re-ran the make command, and there were 43 errors similar to the one below.

Error: DAABandsV2.java:47: error: package gov.nasa.larcfm.ACCoRD does not exist import gov.nasa.larcfm.ACCoRD.Alerter;

Code I am running:

cd utils; javac -cp ../../../daidalus-submodules/v2.0.2/Java/lib/DAIDALUS2.jar DAABandsV2.java DAAMonitorsV2.java && cp -f ../../../daidalus-submodules/v2.0.2/Java/lib/DAIDALUS2.jar ../DAIDALUSv2.0.2.jar && echo "Main-Class: DAABandsV2" > mf && jar umf mf ../DAIDALUSv2.0.2.jar DAABandsV2.class DAAMonitorsV2.class && rm -f mf

I tried to run the files individually in each folder, but I am not able to debug this error. I also tried to modify the path to look for the package, but it still didn't work.

It is my understanding that the package trying to be retrieved can be found at: daa-displays/daidalus-submodules/vx.0.2/Java/src/gov/nasa/larcfm.ACCoRD The file that is trying to retrieve this package and throwing the error is located at: daa-displays/dist/daa-logic/Makefile

Solution

  • Update

    I just found out in an issue of the project, that compilation is only supported on mac/linux machines (I suppose you opened it. Way to go 👍) but you are using Windows.

    Original Answer

    If you find a project with a README.md - file, you should always read that file about any information about how to compile and run the project. The file is usually rendered on the project main page on websites like GitHub:

    In your case the following sections are extremely helpful:

    Requirements:

    The following software is necessary to compile and execute DAA-Displays

    Installation Instructions:

    1. Download the latest release of DAA-Displays from the github repository.
    2. Open a terminal window and change directory to the daa-displays folder.
    3. Run make in the terminal window. This command will download the dependencies and create a folder dist/ with the distribution.
