最近购买了一台新电脑,试图恢复开发Java。我使用的IDE之一,JCreator,已经开始向我发出错误。我在新机器上卸载并重新安装了几次Java,以使一切正常工作。
我有一个语法正确的程序,编译得很好,但每当我尝试从IDE中运行该程序时,它都会显示一条错误消息。它的内容如下:
代码语言:javascript运行复制--------------------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[:

enable assertions with specified granularity
-da[:
-disableassertions[:

-agentlib:
load native agent library
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.com/technetwork/java/javase/documentation/index.html for more details.
Process completed.我假设这仅仅是关于如何挂接运行时环境的说明。
最重要的是,下面的所有运行时设置:
配置>选项> JDK工具>运行应用程序
在我的旧机器上是完全相同的,一切都运行得很好。我知道这肯定是一个JCreator问题,因为我可以从命令行很好地编译所有东西,然后运行它。
javac和java命令可以在命令行中工作,只有这一点在JCreator中不能工作。
对解决这个问题的最佳方法有什么想法吗?
