Eclipse编译Java代码错误-编译器为null

Question

I am newb to android development. I need to compile a java code on eclipse my system was set up to do it. but all of a sudden my pc crashed so I need to setup the new system. I downloaded Jre installed. set up JAVA_HOME variable in my win 2008 r2 machine and downloaded Eclipse Kepler Release and then I try to build the project.

the project has some cmds

cmd /c %JAVA_HOME%/bin/java -jar template.jar dataProvider.java=..\\gen\\com\\data\\dataProvider.java -refresh

but though everything looks like how it was before I was using eclipse juno and jre 6 I guess but now when I build I get the following error.

Compiler is null

Since I am not sure what I missed or the JRE is wrong. I would like some help setting up my machine.

Thanks Appreciated.

下载JDK.exe并安装，然后将环境变量check设置为注释，Joachim会说些什么
