main [@command-file] [parameters] arguments...?
Invokes the main method of a specified bundle.
The command will load the bundle with the given name and invoke the main method of it. The command can be configured similarly as you can configure the repository for build executions.
Any extra arguments specified will be passed to the main method of the bundle.
The command will search for the methods intMain(String) or main(String). It will invoke the one it first finds. If the invoked method is declared to return an integer, then that will be used as an exit code of the process. Use the -system-exit flag to control how this value is interpreted.
File path prefixed with '@' to directly include arguments from the specified file. Each argument is on its separate line. They are directly inserted in place of the @command-file argument. The argument can appear anywhere on the command line. Escaping is not supported for arguments in the command file. The file path may be absolute or relative.
Specifies the name of the class to invoke.
This parameter is used to specify the name of the Java class that is loaded and used to invoke its main method.
If this argument is not specified, the Main-Class attribute of the bundle manifest will be used.
The identifier of the bundle which should be invoked.
The bundle with the specified identifier will be loaded (possibly downloaded from the internet) and the main class of it will be invoked.
If the specified bundle identifier has no version qualifier, then it will be resolved to the most recent version of it.
If this parameter is not specified, the first value for the arguments parameter is used as bundle identifier.
Specifies the identifier of the repository.
The identifier is used to properly determine the configuration user parameters from the -U arguments.
It is "nest" by default.
Specifies how and when the current process should be exited.
This parameter controls whether or not the current process should be exited at the end of the main method invocation.
Exit codes are determined the following way:
- 0: if the main method invocation is successful
- -1: if an exception was thrown
- int: the value returned by the main method (if any)
- none: if there is no exit code
The values may be the following:
- always The current process will always be exited. 0 exit code will be used if there was none.
- on_exception The process will only exit, if there was an exception thrown by the main method. The exit code will be -1.
- forward The process will exit, if there was an exception, or the main method returns an integer.
- never The command will never cause the current process to exit. (Note that the main invocation may still do so.)
Specifies the user parameters for configuring the repository.
This string key-value pairs are interpreted the same way as the -U user parameters for the build execution.
The arguments that are passed as the input to the main method of the invoked class.
Zero, one, or more strings that are directly passed as the String argument of the main method.
If no -bundle is specified, the bundle identifier is determined using the first value of this parameter. In that case that value will not be part of the input arguments.
