[jdt-core-dev] trouble generating parser
|
Hi,
I’m having trouble producing a usable jdt.core plugin after generating
the parser from the grammar. I have not changed the grammar file except
to set the CR/LF to the expected unix format. If I export the plugin
using the parser in the repository, all works as expected.
According to the instructions in jdt-core-home/howto, there should be 21
parser<n>.rsc files, while I get 24. Also, the file
readableNames.properties is created with 0 bytes. I tried using both the
original and empty copies of this file, with the same results.
I am able to build and export a jdt.core plugin with this modified
parser. But when Eclipse is started with this version and a .java file
is opened in an editor, an ArrayIndexOutOfBoundsException is thrown. The
top of the editor pane has the message
“unable to create this part due to an internal error. Reason for the
failure: Editor could not be initialized.”
The stack trace given in the details area is shown at the end of this
message.
Also below is the batch file used to generate the parser. The version of
jikespg used is from a zip file that has 1.3 as its filename, but the
tool reports that it is version 1.2, as defined in globals.c.
Any help would be greatly appreciated. If there’s any additional
information I can provide, please just let me know.
Best regards,
Perry
