我需要有关此概念的帮助。我在这个论坛中搜索了多个主题，但没有一个匹配我的问题。
我写了两个Java类和一个Shell脚本。我将它们压缩到一个文件夹中，然后发送给不懂Java的其他人。他只是解压缩并运行Shell脚本。
此人将在其机器的任何位置提取代码。因此，现在，shell脚本应该执行以下操作。
我的zip文件将包含App.java，Message.java，MyCodeExecution.sh。
#!/bin/bash
export CLASSPATH=$CLASSPATH:.
echo $CLASSPATH
VER=`java -version 2>&1 | grep "java version" | awk '{print $3}'
| tr -d \" | awk '{split($0, array, ".")} END{print array[2]}'`
if [[ $VER -gt 6 ]]; then
echo "Java version is greater than 1.6."
else
echo "Java version is lower than 1.6."

javac App.java
javac Message.java
java App
这是我的Message和App.java代码

答案 0 :(得分：0)
您可以在shell脚本中将类路径设置为当前文件夹，如下所示：
export CLASSPATH = $ CLASSPATH :.
这样，就可以在同一文件夹中找到Player类。
