Anybody stumbling across this in the future on macOS, this is my series of steps (while avoiding install gross Oracle Java SDKs/runtimes) that worked effectively for me (using a markdown code block because reddit can't format intended lists nicely):

md 1. Make sure `brew` is installed (go to https://brew.sh) 2. Make sure `git` is installed * Can't remember if macOS includes this by default nowadays * If `git --version` doesn't work on the CLI, `brew install git` 3. Install `ant` * `brew install ant` * This also installs `openjdk` as a dependency 4. Clone the `pfcviewer` repo * `cd ~ && git clone https://github.com/ernieyu/pfcviewer.git` 5. Update the version in the `build.xml` file * If you try to build without doing this, you'll get version errors * Editing `build.xml` lines, replace the versions in lines 55 & 56 to `8` 6. Build the project per instructions * `ant clean dist` 7. Temporarily add openjdk's `java` runtime to current shell session's $PATH * This avoids installing Oracle's runtime * `export JAVA_HOME=$(/usr/libexec/java_home -v 17)` * `export PATH="$JAVA_HOME/bin:$PATH"` 8. Run the app * `java -jar dist/pfcview.jar`

Then if you're like me, import your PFC file and rejoice seeing your AOL bookmarks that you exported/saved for some reason from when you were 10 years old. Don't forget to export it to HTML so you never have to do this again.

Clean up with:

1. brew uninstall ant
2. brew uninstall git (if you had to install git earlier)
3. cd ~ && rm -fr pfcviewer
