Sorry GNU make does not support this directly.

I suggest you read "Managing Projects with GNU Make".

In this book on chapter about Java writted that calling

$ java file_1.java
....
$ java file_n.java

get too long time, but "java" command support syntax

$ java @file-list

where in file-list listen all *.java in your project.

So do:

compile-java: javafile
    java @$< --output $(dist-dir)

javafile: $(wildcard *.java)
    echo $^ >$<
