環境を変えた時、Javaのクラスパスを指定しても読み込めないとき

More than 3 years have passed since last update.

区切り文字を忘れている

Javaのクラスパスを「-cp」オプションで指定する時、環境によって違うので忘れないように。

  • Windows系:「;」(セミコロン)
  • UNIX系:「:」(コロン)

例)Linuxの場合
java -jar -cp "piyo.jar:fuga.jar:." hoge.jar

複数のコマンドを指定するときの終端文字が違う

こちらはクラスパスとは直接関係ないがシェルに組み込んだ時などよく忘れる。
- Windows系:「&」(アンパサンド)
- UNIX系:「;」(セミコロン)

例)
java -jar hogera.jar ; java -jar hogehoge.jar
