和我一样使用Main.java，HelloServlet.java，index.jsp的

Answer 1

的JVM告诉你它找不到类launch.Main。您需要设置的类路径JVM找到它：

java -cp <f> launch.Main 

其中<f>是路径到包含启动目录（例如，目标/箱）

Answer 2

在Windows上，你需要运行的文件夹：

target\bin\webapp.bat 

Answer 3

不知道，如果你还在乎这个，但是你做的事：

set REPO=%UserProfile%\.m2\repository 

？ appassembler生成的target/bin/webapp脚本依赖于该环境变量。
