一、前缀~

最近重新看Java,别人推荐了一款轻量级的IDE，没错，就是JCreator。

它主要有两个版本：Pro和LE版本，其中Pro收费，LE版免费，但是功能相对于Pro更不齐全。

我下载的是csdn上的Pro破解版，传送门：http://download.csdn.net/download/liujun13579/4430786

安装完后感觉蛮不错的，又小又快，界面有点模范vs的感觉~

二、问题描述

废话不多说，先说说问题：

情形：某个文件夹中有一个test.java文件，我双击打开（默认使用JCreator），但是当我F5编译和运行时，

问题出现了。

首先是编译，没有问题，编译成功，也产生了.class文件

然后调转到运行窗口，问题来了：

--------------------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. -D= set a system property -verbose[:class|gc|jni] enable verbose output -version print product version and exit -version: require the specified version to run -showversion print product version and continue -jre-restrict-search | -no-jre-restrict-search include/exclude user private JREs in the version search -? -help print this help message -X print help on non-standard options -ea[:...|:] -enableassertions[:...|:] enable assertions with specified granularity -da[:...|:] -disableassertions[:...|:] disable assertions with specified granularity -esa | -enablesystemassertions enable system assertions -dsa | -disablesystemassertions disable system assertions -agentlib:[=] load native agent library , e.g. -agentlib:hprof see also, -agentlib:jdwp=help and -agentlib:hprof=help -agentpath:[=] load native agent library by full pathname -javaagent:[=] load Java programming language agent, see java.lang.instrument -splash: show splash screen with specified image See http://www.oracle.co...tion/index.html for more details.

以上明显就是你在命令行输入java时出现的帮助文档，我就在想可能是配置出了问题：

于是在Configure中检查，没有发现问题...

于是我打开了Options-->JDK Tools-->run application中的show command line，想看看具体的命令

再次运行，果然，问题出现了：

以下是执行的命令：

Command : "D:\jdk\bin\java.exe" -classpath "F:\学习笔记\java学习笔记\java代码\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"

你是否发现好像少了点什么？没错，怎么最后没有跟文件名啊！！

正常情况应该是（java test），但在这里test不见了~~

问题是发现了，但是如何解决呢？

三、解决问题

于是我就在百度上查找，但是很多都是错误的答案，于是俺就上Google找，

输入 JCreator can‘t run，查询，google果然不负我啊，第一条就是答案~

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.

The default VM is server.

-cp

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!

大概的意思就是说：碰到了和我我一样的问题，如何解决，最后他抱怨说LE版本没问题，反倒是花了钱买的却不能运行~~（俺用的是盗版，就不好跟着起哄了~）

最后，经过和管理员的一系列探讨：这是bug....

需要等待更新，暂时的解决办法有以下几个：

1.建立一个projiect，每次打开projiect来运行，这样就没有问题

2.不要直接从文件打开JCreator，而是先打开JCreator，并且保证start page tab打开了，然后再点击open打开文件，这个时候就能运行了~！

如果你有好的解决办法，请留言告诉我哦~！
