Clean Build Java Command Line

问题

I am compiling my project written using eclipse using the command line as follows

javac file.java

And then to run:

java file (args here)

How would I run a clean build, or compilation? Whenever I recompile, the changes are not getting affected unless I delete all the .class files and recompile. Please note that the the main file will call other classes too.

Thanks

You should compile all the Java files in your application to be sure, basically.

Options include:

• Use a full build system such as Ant.

• On a Unix box, use something like:

  javac `find . -name '*.java'`
  

  assuming you don't have too many (or use xargs if necessary).

• If you're not using packages (and you really should be) you can just use:

  javac *.java
