Fixes gh-152.
... to ease excluding dependencies
eckage changed to bootRepackage
- Register BootRepackage order to use task foo(type: BootRepackage){}
- Allow user to use customConfiguration

Spring Boot - Loader Tools
The Spring Boot Loader Tools module provides support utilities to help when creating Spring Boot Loader compatible archives. This module is used by the various build system plugins that we provide.
Note: The quickest way to build a compatible archive is to use the spring-boot-maven-plugin or spring-boot-gradle-plugin.
Repackaging archives
To repackage an existing archive so that it becomes a self-contained executable archive
use org.springframework.boot.loader.tools.Repackager. The Repackager class takes a
single constructor argument that refers to an existing jar or war archive. Use one of the
two available repackage() methods to either replace the original file or write to a new
destination. Various settings can also be configured on the repackager before it is
run.
Libraries
When repackaging an archive you can include references to dependency files using the
org.springframework.boot.loader.tools.Libraries interface. We don't provide any
concrete implementations of Libraries here as they are usually build system specific.
If your archive already includes libraries you can use Libraries.NONE
Finding a main class
If you don't use Repackager.setMainClass() to specify a main class, the repackager will
use ASM to read class files and attempt to find a suitable class.
The first class with a public static void main(String[] args) method will be used.
Searching is performed using a breadth first algorithm, with the assumption that the main
class will appear high in the package structure.
Example
Here is a typical example repackage:
Repackager repackager = new Repackager(sourceJarFile);
repackager.setBackupSource(false);
repackager.repackage(new Libraries() {
@Override
public void doWithLibraries(LibraryCallback callback) throws IOException {
// Build system specific implementation, callback for each dependency
// callback.library(nestedFile, LibraryScope.COMPILE);
}
});
Further Reading
For more information on how Spring Boot Loader archives work take a look at the spring-boot-loader module. If you want to see how we use this library the Maven and Gradle plugins are good place to start.
