Cant install on Luna
Submitted by Silvia Takahashi on Wed, 08/17/2016 - 12:47
I install, relaunch eclipse but the plugin is not installed. It appears under installed software, but I cannot create a new javaCC project, nor can I ru JavaCC on an imported project.

Doesn't support installation on Eclipse Neon. Is it planned or is the plug-in dead?

The plugin works on Neon and below. May be the installation from the Eclipse Market Place does not work (because things have not been updated ?). You can still install it by going to SourceForge.
Java CC version
Submitted by Gabriele Pezzini on Thu, 09/10/2020 - 10:09
The plugin has the javacc version 1.5.33, which is of some years ago.
Right now java cc is at level 7.0.9.
Have in in plan to support the newer version of javacc or are there any ways to use the newer version of java CC in this plugin?
Thanks

In reply to Java CC version by Gabriele Pezzini
Hi. 1.5.33 is the plugin's version, not javacc's version. The plugin embeds some versions of javacc and jtb, but you can set for each project any javacc.jar that you have downloaded on your workstation.
JavaCC / JJDoc does not handle spaces in file paths properly
Submitted by WANDERSON RIGO on Tue, 04/25/2023 - 10:13
Hello. I installed the JavaCC plugin on Eclipse 2023. However, when I try to generate documentation for a .jj file using the menu, the HTML file is not generated. I suspect that the reason is because the path to the .jj file contains a whitespace, which is not being handled properly. I was able to generate the HTML file by creating a .bat file with the following content:
java -classpath C:\Users\Wanderson.p2\pool\plugins\sf.eclipse.javacc_1.5.33\jars\javacc-6.0.jar jjdoc -OUTPUT_FILE=C:\Users\Wanderson\Downloads\ParserBNF.html "D:\IFC\Google Drive\MyProject\src\lookahead\Lookahead.jj"
Note that the paths are enclosed in quotation marks to handle the space in "Google Drive".
On the other hand, the JavaCC console in Eclipse says:
java -classpath C:\Users\Wanderson.p2\pool\plugins\sf.eclipse.javacc_1.5.33\jars\javacc-6.0.jar jjdoc -OUTPUT_FILE=C:\Users\Wanderson\Downloads\ParserBNF.html D:/IFC/Google Drive/aulas/Compiladores/eclipse/JavaCC/src/lookahead/Lookahead.jj
