错误：从Linux命令行运行时找不到或加载主类Main-

Question

Originally, I was able to run my code from command line as such:

java -cp "/var/www/html/tcqa/bin/test_and_control-1.0-SNAPSHOT.jar:/var/www/html/tcqa/bin/postgresql-9.3-1100-jdbc41.jar" Main /var/www/html/tcqa/sql/tc.sql

I needed to add some new functionality and decided to break out the main class and use case to manage which sql statement would get run. I moved my main class out and have not been able to get my code to run from command line. My new command line looks like this:

java -cp ["/home2/smontoya/test_and_control-1.0-SNAPSHOT.jar:/var/www/html/tcqa/bin/postgresql-9.3-1100-jdbc41.jar;"] Main email /var/www/html/tcqa/sql/email.sql

Obviously I want to test this before moving it into production mode. My code structure looks like this:

main
|-->java
    |--> email
    |    |__ EmailFlag
    |    |__ EmailRow
    |--> tc
    |    |__  Analytics
    |    |__ Row
    |    |__  TestAndControl
    |    |__  Utils
    |--> Main

Answer 1

Please check your manifest file in the jar.. It describes the version and mainClass. If you are using maven .. While adding dependencies to build jar describe the main class in configuration so that maven will add this configuration to manifest file

Answer 2

尝试指定Main的标准名称：

java -cp /path1:/path2 com.company.Main arg1 arg2
