メークファイルが他のクラスを見つけられません（Java、Linux、Ubuntu）

私のクラスのメイクファイルを作成しようとしていますが、同じフォルダにありますが、メークファイルは見えません。メークファイルが他のクラスを見つけられません（Java、Linux、Ubuntu）

javacを実行すると動作しますが、makefileを実行しても動作しません。

：

Makefileの

JAVAC=/usr/bin/javac 
dir=src/myrepo 

.SUFFIXES: .java .class 

.java.class: 

     $(JAVAC) -cp . $< 

default: $(dir)/*.class 

clean: 
     if [ -e $(dir)/*.java~ ] ; then rm $(dir)/*.java~; fi 
     mv $(dir)/*.class bin; fi

ディレクトリはAssignment/Makefile、Assignment/src/myrepo（myrepoのすべてのクラス）

クラスですPrintIt.java、BinarySearchTree.java、BinaryTree.java、Record.java（myrepoのすべて）

エラーです

「dir =/src/myrepo」を試してください。スラッシュを忘れているようです。 – Naidu

クラスパスが間違っているようです。カレントディレクトリを使用しますが、 "./src"ではありませんか？ myrepoはパッケージ名であると仮定します。 – vanje

また、Maven、Gradle、AntなどのJava固有のビルドツールを使用することを検討する必要があります。 MakeとJavaは親友ではありません。 – vanje

：

# Assignment 1 makefile 
# Hendri Vermeulen 
# 29 March 2017 

JAVAC=/usr/bin/javac 
dir=src/myrepo 

.SUFFIXES: .java .class 

.java.class: 
     $(JAVAC) -cp src/myrepo $< 

default: $(dir)/Record.class $(dir)/BinaryTree.class $(dir)/BinarySearchTree.cla 

clean: 
     if [ -e $(dir)/*.java~ ] ; then rm $(dir)/*.java~; fi 
     mv $(dir)/*.class bin; fi

は、コンパイルコマンド、私のクラスパスのディレクトリで "SRC/myrepo -cp" を追加する必要がありました。
