# jbang
|
||
|
|
|
||
|
|
> Easily create, edit and run self-contained source-only Java programs.
|
||
|
|
> See also: `java`.
|
||
|
|
> More information: <https://www.jbang.dev/documentation/guide/latest/cli/jbang.html>.
|
||
|
|
|
||
|
|
- Initialize a simple Java class:
|
||
|
|
|
||
|
|
`jbang init {{path/to/file.java}}`
|
||
|
|
|
||
|
|
- Initialize a Java class (useful for scripting):
|
||
|
|
|
||
|
|
`jbang init --template={{cli}} {{path/to/file.java}}`
|
||
|
|
|
||
|
|
- Use `jshell` to explore and use a script and any dependencies in a REPL editor:
|
||
|
|
|
||
|
|
`jbang run --interactive`
|
||
|
|
|
||
|
|
- Setup a temporary project to edit a script in an IDE:
|
||
|
|
|
||
|
|
`jbang edit --open={{codium|code|eclipse|idea|netbeans|gitpod}} {{path/to/script.java}}`
|
||
|
|
|
||
|
|
- Run a Java code snippet (Java 9 and later):
|
||
|
|
|
||
|
|
`{{echo 'Files.list(Paths.get("/etc")).forEach(System.out::println);'}} | jbang -`
|
||
|
|
|
||
|
|
- Run command line application:
|
||
|
|
|
||
|
|
`jbang {{path/to/file.java}} {{command}} {{arg1 arg2 ...}}`
|
||
|
|
|
||
|
|
- Install a script on the user's `$PATH`:
|
||
|
|
|
||
|
|
`jbang app install --name {{command_name}} {{path/to/script.java}}`
|
||
|
|
|
||
|
|
- Install a specific version of JDK to be used with `jbang`:
|
||
|
|
|
||
|
|
`jbang jdk install {{version}}`
|
