如何编译多个* .java文件

Question

Someone gave me their code: several *.java files under same directory (src\\eval\\*.java). I guess they are multiple source code files in the same project.

When trying to compile (under windows), I typed

javac -sourcepath src\eval\AlnEval.java -d bin

but I get this error when doing so:

javac: no source file.

---

Tried

javac src\eval\AlnEval.java

Many errors in compilation. Seems AlnEval.java uses several classes defined in other *.java files.

Answer 1

您可以键入javac *.java或更好地使用和IDE（例如eclipse）

Answer 2

To compile multiple files in one go, you just do

javac src\eval\*.java

That's it!

Answer 3

$ cd src/eval
$ javac *.java

Answer 4

try below code

first go to your main src directory

javac -cp .;lib/<YOU_JARS>.jar -d bin  packA/*.java

Answer 5

Try to set the classpath to include the external dependencies. If you have all the dependencies as jar files in a lib directory, for example, you can use

java -cp lib\* src\eval\*.java

This includes all the dependencies needed to compile the app.
