一、字首~
最近重新看Java,别人推薦了一款輕量級的IDE，沒錯，就是JCreator。
它主要有兩個版本：Pro和LE版本，其中Pro收費，LE版免費，但是功能相對于Pro更不齊全。
我下載下傳的是csdn上的Pro破解版，傳送門：http://download.csdn.net/download/liujun13579/4430786
安裝完後感覺蠻不錯的，又小又快，界面有點模範vs的感覺~
二、問題描述
廢話不多說，先說說問題：
情形：某個檔案夾中有一個test.java檔案，我輕按兩下打開（預設使用JCreator），但是當我F5編譯和運作時，
問題出現了。
首先是編譯，沒有問題，編譯成功，也産生了.class檔案
然後調轉到運作視窗，問題來了：
--------------------Configuration:
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available
-server to select the "server" VM
-hotspot is a synonym for the "server" VM [deprecated]
The default VM is server.
-cp
-classpath
A ; separated list of directories, JAR archives,
and ZIP archives to search for class files.

-javaagent:

-splash:

以上明顯就是你在指令行輸入java時出現的幫助文檔，我就在想可能是配置出了問題：
于是在Configure中檢查，沒有發現問題...
于是我打開了Options-->JDK Tools-->run application中的show command line，想看看具體的指令
再次運作，果然，問題出現了：
以下是執行的指令：
Command : "D:\jdk\bin\java.exe" -classpath "F:\學習筆記\java學習筆記\java代碼\test;D:\jdk\jre\lib\rt.jar;D:\jdk\lib\dt.jar;D:\jdk\lib\tools.jar;D:\jdk\jre\lib\ext\dnsns.jar;D:\jdk\jre\lib\ext\localedata.jar;D:\jdk\jre\lib\ext\sunjce_provider.jar;D:\jdk\jre\lib\ext\sunmscapi.jar;D:\jdk\jre\lib\ext\sunpkcs11.jar"
你是否發現好像少了點什麼？沒錯，怎麼最後沒有跟檔案名啊！！
正常情況應該是（java test），但在這裡test不見了~~
問題是發現了，但是如何解決呢？
三、解決問題
于是我就在百度上查找，但是很多都是錯誤的答案，于是俺就上Google找，
輸入 JCreator can‘t run，查詢，google果然不負我啊，第一條就是答案~
以下是老外的原文：
I have JCreator Pro 5.00.016
Up until today everything was fine. I ran a program this morning and everything worked just fine, now when I try and run it I get the following output.
Please let me know what I can do to correct this.
Thank you.

Update:
Still will not run in Pro version.
It will run in the LE version.
Would like to know what to do as I have paid for Pro and am not able to use it!
大概的意思就是說：碰到了和我我一樣的問題，如何解決，最後他抱怨說LE版本沒問題，反倒是花了錢買的卻不能運作~~（俺用的是盜版，就不好跟着起哄了~）
最後，經過和管理者的一系列探讨：這是bug....
需要等待更新，暫時的解決辦法有以下幾個：
1.建立一個projiect，每次打開projiect來運作，這樣就沒有問題
2.不要直接從檔案打開JCreator，而是先打開JCreator，并且保證start page tab打開了，然後再點選open打開檔案，這個時候就能運作了~！
如果你有好的解決辦法，請留言告訴我哦~！
