@Restricted(value=org.kohsuke.accmod.restrictions.NoExternalUse.class)
public class HttpRetriever
extends org.jenkinsci.plugins.workflow.libs.LibraryRetriever

The goal of this plugin is to provide another way to retrieve shared libraries via the @Library declaration in a Jenkinsfile.

The current official plugin (workflow-cps-global-lib) does provide only a way to retrieve shared libraries through a SCM, such as Git, Subversion, etc.

Parameters:

name - Name of the library (as specified in the Jenkinsfile @Library)

version - Version of the library (as specified in the Jenkinsfile @Library)

target - Where the code should be retrieved

run - Jenkins context

listener - Only used to get the logger

Throws:

Exception - if the file cannot be downloaded, archive can't be extracted, workspace is not writable

retrieve

public void retrieve(@Nonnull
                     String name,

              throws Exception

Checks first if the library is accessible via a HEAD call. Then retrieves the shared library through HTTP protocol.

Specified by:

retrieve in class org.jenkinsci.plugins.workflow.libs.LibraryRetriever

Parameters:

name - Name of the library (as specified in the Jenkinsfile @Library)

version - Version of the library (as specified in the Jenkinsfile @Library)

changelog - Not used

target - Where the code should be retrieved

run - Jenkins context

validateVersion

public FormValidation validateVersion(@Nonnull
                                      String name,
                                      @Nonnull
                                      String version)

Validates version. Is it available for download. Tests the URL. Used if a default version is referenced in the declaration of the library. Then the archive of the library must be reachable.

Replaces the pattern ${library.NAME.version} in the URL (if found in the shared library URL) either by the default version specified in the admin configuration page or by the user in the Jenkinsfile @Library call.

Overrides:

validateVersion in class org.jenkinsci.plugins.workflow.libs.LibraryRetriever

Parameters:

name - Name of the library

version - Version of the library

Returns:

Result of the validation

getDescriptor

public org.jenkinsci.plugins.workflow.libs.LibraryRetrieverDescriptor getDescriptor()

Specified by:

getDescriptor in interface Describable<org.jenkinsci.plugins.workflow.libs.LibraryRetriever>

Overrides:

getDescriptor in class org.jenkinsci.plugins.workflow.libs.LibraryRetriever
