Hey folks!

I have a noob question. I'm trying to follow the very basic step in https://javacc.com/home/

git clone https://github.com/javacc21/javacc21.git
cd javacc21
ant

I'm getting a compile error in that last ant step (see below). May I get some help to resolve this? I am using a pretty fresh installation of Linux and Java and maybe I missed out something. This is my Java version

BUILD FAILED
/home/al/projects/javacc21/build.xml:82: Compile failed; see the compiler error output for details.

Total time: 1 second

Hi, thanks for the message. I'm a bit puzzled. The reason it's not finding all the various classes, like Node and BaseNode and all that is that the parser-gen task was not run for some reason. You can see that in the output even, that you have:

   parser-gen:

   preprocessor-gen:

So it's doing nothing for those steps. When I run it on my local box, I get:

 parser-gen:
     [echo] Using Bootstrap JavaCC to regenerate JavaCC parser

 preprocessor-gen:
     [echo] Using Bootstrap JavaCC to regenerate preprocessor

IOW, it's generating the java code for both the JavaCC parser (and the preprocessor which is a separate parser actually). Now, I'm really a bit puzzled by what you're reporting. It seems as if the build system (which is not terribly complex) "thinks" that the rebuild of the parser classes is not necessary, so it's skipping that step and then going straight to the compile, but some of the needed classes are not present because the parser-gen step was (incorrectly) skipped.

Now, one thing you could try is just building the parser by directly running JavaCC21 on the grammars in question. So, from the top-level directory, you could just try:

    bin/javacc src/javacc/JavaCC.javacc
    bin/javacc examples/preprocessor/Preprocessor.javacc

And then, assuming that worked, do:

  ant compile

So maybe try that and tell us what happens!

  • alr replied to this.

    The build process uses the timestamp of the files to detect things needed to be done.
    "git clone" timestamps files as they are extracted, so the timestamps of the files to be generated may be newer than the source.
    So for me "ant clean" usually does the trick.
    "ant full-test" will also do a clean first.

    • alr replied to this.

      Gravelbones

      That did the trick! ant full-test worked and now ant compile works too.

        revusky

        I understand why Gravelbones's trick might work but I don't understand how the problem happened in the first place. I can't even seem to replicate the problem either. Maybe there was something strange in my machine? In any case, it's all settled now. Thanks!

          Okay, that´s good to hear. I have to admit that I was puzzled by what you were reporting because I honestly didn't see how this problem was even possible. Well, never mind. If you hit any more snags, you now where to find us!
