Method Detail

mapDescriptorToClassLoader

Resolver.ClassLoaderDescriptor mapDescriptorToClassLoader(InputStream descriptor)

Creates a classloader from the passed descriptor (dependencies.txt). WARNING: note it is very important to close the descriptor once no more used otherwise you can leak memory.

Parameters:

descriptor - the dependencies.txt InputStream.

Returns:

the classloader initialized with the resolved dependencies.

mapDescriptorToClassLoader

default Resolver.ClassLoaderDescriptor mapDescriptorToClassLoader(List<String> gavs)

Alias to load dependencies from a plain list of gav (groupId:artifactId:version).

Parameters:

gavs - the dependencies to use to resolve dependencies.

Returns:

the collection of file representing the available dependencies.

resolveFromDescriptor

Collection<File> resolveFromDescriptor(InputStream descriptor)

Resolves the dependencies from the descriptor passed as an InputStream. IMPORTANT: this is to use when you are sure the file is resolvable if you don't have a fallback. In that last case, prefer the mapDescriptorToClassLoader.

Parameters:

descriptor - the dependencies.txt to use to resolve dependencies.

Returns:

the collection of file representing the available dependencies.

resolveFromDescriptor

default Collection<File> resolveFromDescriptor(List<String> gavs)

Alias to load dependencies from a plain list of gav (groupId:artifactId:version).

Parameters:

gavs - the dependencies to use to resolve dependencies.

Returns:

the collection of file representing the available dependencies.
