All I know is that it's stopping antlr from generating, I apologize. Here's the log file:

I got the same error with a simple grammar for logical formulas. For me the problem was, that ANTLR could not find an obvious start rule because I had a recursion on my intended start rule. Adding a new rule pointing to the recursive one did the job (see http://thesoftwarelife.blogspot.com/2008/07/antlr-frustrations.html).
It's a pity that ANTLR IDE does not correctly forward the error message. On the command line i get:
warning(138): Formula.g:0:1: grammar Formula: no start rule (no rule can obviously be followed by EOF)
I had the same problem yesterday. Not sure if my case is identical to yours but it worth a try. I had a rule named annotation like this:
annotation
: AT class declaration?
-> ^(ANNOTATION class declaration?)
;
And I wanted to parse sub annotations in curly braces so I did:
subAnnotation:
: CURLY_START annotation CURLY_END
-> ^(ANNOTATION annotation)
;
This was given me the same error has yours. So, I end up wondering with it is not working. Even if I'm unsure, I think the problem is the recursion of the annotation rule that was causing the error. So, I ended up doing this:
annotationValue:
: CURLY_START subAnnotation CURLY_END
-> ^(ANNOTATION subAnnotation)
;
subAnnotation
: AT class declaration?
-> ^(ANNOTATION class declaration?)
;
This resolved my problem. Like I said, I don't know if this fix can be applied to your problem. Moreover, I thought that ANTLR was able to deal with non-left-recursive rule. Maybe someone with a better knowledge of the tool could confirm it.
I must admit I did not try the suggestion of #BartKiers, maybe it would also solve the problem.

I'm trying to fix errors which are reported by forbiddenapis. I had that line:
paramMap.put(Config.TITLEBOOST.toUpperCase(), titleBoost);
So, its been reported as error as usual. I've tried that:
paramMap.put(Config.TITLEBOOST.toUpperCase(Locale.getDefault()), titleBoost);
and that:
paramMap.put(Config.TITLEBOOST.toUpperCase(Locale.ROOT), titleBoost);
also that:
paramMap.put(Config.TITLEBOOST.toUpperCase(Locale.ENGLISH), titleBoost);
However none of them fixed the error:
[forbiddenapis] Forbidden method invocation:
java.lang.String#toUpperCase() [Uses default locale]
What I miss?
Double-check that the bytecode you are analyzing is actually your most recent build output, and that you're looking at the same line forbiddenapis is :) . This looks to me like your source/bytecode/analysis are falling out of sync — the relevant rule shouldn't flag an error on String.toUpperCase(Locale).
Disclaimer: I haven't used forbiddenapis myself --- I wrote this answer based on the repo and on a blog post I found.
I'm trying the quickstart from here: http://datafu.incubator.apache.org/docs/datafu/getting-started.html
I tried nearly everything, but I'm sure it must be my fault somewhere. I tried already:
exporting PIG_HOME, CLASSPATH, PIG_CLASSPATH
starting pig with -cpdatafu-pig-incubating-1.3.0.jar
registering datafu-pig-incubating-1.3.0.jar locally and in hdfs => both succesful (at least no error shown)
nothing helped
Trying this on pig:
register datafu-pig-incubating-1.3.0.jar
DEFINE Median datafu.pig.stats.StreamingMedian();
data = load '/user/hduser/numbers.txt' using PigStorage() as (val:int);
data2 = FOREACH (GROUP data ALL) GENERATE Median(data);
or directly
data2 = FOREACH (GROUP data ALL) GENERATE datafu.pig.stats.StreamingMedian(data);
I get this name-resolve error:
2016-06-04 17:22:22,734 [main] ERROR org.apache.pig.tools.grunt.Grunt
- ERROR 1070: Could not resolve datafu.pig.stats.StreamingMedian using imports: [, java.lang., org.apache.pig.builtin.,
org.apache.pig.impl.builtin.] Details at logfile:
/home/hadoop/pig_1465053680252.log
When I look into the datafu-pig-incubating-1.3.0.jar it looks OK, everything in place. I also tried some Bag functions, same error then.
I think it's kind of a noob-error which I just don't see (as I did not find particular answers for datafu in SO or google), so thanks in advance for shedding some light on this.
Pig script is proper, the only thing that could break is that while registering datafu there were some class dependencies that coudn't been met.
Try to run locally (pig -x local) and see a detailed log.
Check also the version of pig - it should be newer than 0.14.0.
With reference to my previous question,
Executing a lisp function from Java
I was able to call lisp code from Java using ABCL.
But the problem is, the already existing lisp code uses CL-PPCRE package.
I can not compile the code as it says 'CL-PPCRE not found'.
I have tried different approaches to add that package,
including
1) how does one compile a clisp program which uses cl-ppcre?
2)https://groups.google.com/forum/#!topic/cl-ppcre/juSfOhEDa1k
Doesnot work!
Other thing is, that executing (compile-file aima.asd) works perfectly fine although it does also require cl-pprce
(defpackage #:aima-asd
(:use :cl :asdf))
(in-package :aima-asd)
(defsystem aima
:name "aima"
:version "0.1"
:components ((:file "defpackage")
(:file "main" :depends-on ("defpackage")))
:depends-on (:cl-ppcre))
The final java code is
interpreter.eval("(load \"aima/asdf.lisp\")");
interpreter.eval("(compile-file \"aima/aima.asd\")");
interpreter.eval("(compile-file \"aima/defpackage.lisp\")");
interpreter.eval("(in-package :aima)");
interpreter.eval("(load \"aima/aima.lisp\")");
interpreter.eval("(aima-load 'all)");
The error message is
Error loading C:/Users/Administrator.NUIG-1Z7HN12/workspace/aima/probability/domains/edit-nets.lisp at line 376 (offset 16389)
#<THREAD "main" {3A188AF2}>: Debugger invoked on condition of type READER-ERROR
The package "CL-PPCRE" can't be found.
[1] AIMA(1):
Can anyone help me?
You need to load cl-ppcre before you can use it. You can do that by using (asdf:load-system :aima), provided that you put both aima and cl-ppcre into locations that your ASDF searches.
I used QuickLisp to add cl-ppcre (because nothing else worked for me).
Here is what I did
(load \"~/QuickLisp.lisp\")")
(quicklisp-quickstart:install)
(load "~/quicklisp/setup.lisp")
(ql:quickload :cl-ppcre)
First 2 lines are only a one time things. Once quickLisp is installed you can start from line 3.
I'm using the owl2java plugin to generate Java code from an Ontology file. But I'm always getting de same error.

I have no idea about what I'm doing wrong. Any Ideas?
Thanks you a lot.
I looked at the top line on your exception, and see com.hp.hpl.jena.ontology.impl.TransitivePropertyImpl.
Googling for that leads to a version of the source code. It may not be exactly the same version as you're using, but is probably close enough to be informative. Reading the code leads to these questions:
Does your Model have a profile? It must.
Does the profile support Transitivity? It must.
Are you combining Transitive with something else that it's incompatible with?
In both the Joy of Clojure and on Alex Miller's Pure Danger Tech blog-post it is recommended that you can print the last stack using something like the following:
(use 'clojure.stacktrace)
(java.util.Date. "foo")
(.printStackTrace *e 5)
But I can't get any of their examples to work, and instead just get
java.lang.NullPointerException: null
Reflector.java:26 clojure.lang.Reflector.invokeInstanceMethod
(Unknown Source) jtown$eval9755.invoke
What's up with this? .printStackTrace seems to be a Java function from the looks of it, so I am not sure why I am bringing clojure.stacktrace into my namespace, in the first place. I read through the clojure.stacktrace API, though, and see an e function, which seems similar too but is not the *e function, which is in core and is supposed to be binding to the last exception, but isn't. Could somebody straighten me out on the best way to check stack-traces?
There are some special vars available when using the REPL and
*e - holds the result of the last exception.
For instance:
core=> (java.util.Date. "foo")
IllegalArgumentException java.util.Date.parse (Date.java:615)
core=> (class *e)
java.lang.IllegalArgumentException
core=> (.printStackTrace *e)
java.lang.IllegalArgumentException
at java.util.Date.parse(Date.java:615)
<not included.....>
You are right, .printStackTrace is the java method that is invoked on the exception class. This is not very straightforward (since its java interop) so clojure.stacktrace namespace has some utilities about working with stack traces
So after
(use 'clojure.stacktrace)
you can use the stacktrace library instead of java interop:
core=> (print-stack-trace *e)
java.lang.IllegalArgumentException: null
at java.util.Date.parse (Date.java:615)
<not included.....>
Obviously in an app, instead of *e, you can do a try - catch and use the related functions as necessary
I use
(.printStackTrace *e *out*)
That seems to work.
