java - Unresolved compilation but library already in classpath -


i'm facing weird problem trying build component:

https://github.com/theclue/talend-components-collection/tree/master/twitter/ttwitterstreaminput

this custom component talend open studio, actually, problem seems more general , it's not related talend.

the unresolved compilation problems related 2 classes located in twitter4j-stream-4.0.1.jar

the library correctly imported , linked, may see command use execute it:

c:/program files (x86)/java/jre7/bin/java.exe -xms256m -xmx1024m -verbose -dfile.encoding=utf-8 -cp e:/talendworkspaces/.java/lib/dom4j-1.6.1.jar;e:/talendworkspaces/.java/lib/guava-13.0.jar;e:/talendworkspaces/.java/lib/talend-bridge-api-0.2.jar;e:/talendworkspaces/.java/lib/ttwitterstreaminput-1.1.jar;e:/talendworkspaces/.java/lib/twitter-commodities-0.2.jar;e:/talendworkspaces/.java/lib/twitter4j-core-4.0.1.jar;e:/talendworkspaces/.java/lib/twitter4j-stream-4.0.1.jar;.;e:/talendworkspaces/.java/classes;e:/talendworkspaces/.java/lib; test.twitterstream_0_1.twitterstream

but exeception leaves no doubt:

exception in thread "main" java.lang.error: unresolved compilation problems:      method addlistener(statuslistener) type talendrowtweetbehaviour refers missing type statuslistener     method addfilter(filterquery) type talendrowtweetbehaviour refers missing type filterquery      @ test.twitterstream_0_1.twitterstream.ttwitterstreaminput_1process(twitterstream.java:737)     @ test.twitterstream_0_1.twitterstream.ttwitteroauth_1process(twitterstream.java:429)     @ test.twitterstream_0_1.twitterstream.runjobintos(twitterstream.java:1241)     @ test.twitterstream_0_1.twitterstream.main(twitterstream.java:1100)

using -verbose command line parameter can check loaded classes. effectively, statuslistener , filterquery not loaded. i've no clue on why thery not, since library available , explicited in classpath!

edit: added screenshot better clarity. i'm wondering why unresolved class declared @ line 733 error @ line 737 only...

enter image description here

i noticed twitter jar declared e:/talendworkspaces/.java/lib/ttwitterstreaminput-1.1.jar. sure small 't' @ beginning? seems java can't find jar due wrong filename.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
