public class Signature extends org.gradle.api.internal.artifacts.publish.AbstractPublishArtifact
A digital signature file artifact.

A signature file is always generated from another file, which may be a PublishArtifact.

  • Constructor Details

    • Signature

      public Signature(PublishArtifact toSign, SignatureSpec signatureSpec, Object... tasks)
      Creates a signature artifact for the given public artifact.

      The file to sign will be the file of the given artifact and the classifier of this signature artifact will default to the classifier of the given artifact to sign.

      The artifact to sign may change after being used as the source for this signature.

      Parameters:
      toSign - The artifact that is to be signed
      signatureSpec - The specification of how the artifact is to be signed
      tasks - The task(s) that will invoke generate() on this signature (optional)
    • Signature

      public Signature(File toSign, SignatureSpec signatureSpec, Object... tasks)
      Creates a signature artifact for the given file.
      Parameters:
      toSign - The file that is to be signed
      signatureSpec - The specification of how the artifact is to be signed
      tasks - The task(s) that will invoke generate() on this signature (optional)
    • Signature

      public Signature(File toSign, String classifier, SignatureSpec signatureSpec, Object... tasks)
      Creates a signature artifact for the given file, with the given classifier.
      Parameters:
      toSign - The file that is to be signed
      classifier - The classifier to assign to the signature (should match the files)
      signatureSpec - The specification of how the artifact is to be signed
      tasks - The task(s) that will invoke generate() on this signature (optional)
    • Signature

      public Signature(Closure<File> toSign, Closure<String> classifier, SignatureSpec signatureSpec, Object... tasks)
      Creates a signature artifact for the file returned by the toSign closure.

      The closures will be “evaluated” on demand whenever the value is needed (e.g. at generation time)

      Parameters:
      toSign - A closure that produces a File for the object to sign (non File return values will be used as the path to the file)
      classifier - A closure that produces the classifier to assign to the signature artifact on demand
      signatureSpec - The specification of how the artifact is to be signed
      tasks - The task(s) that will invoke generate() on this signature (optional)
    • Signature

      public Signature(Callable<File> toSign, Callable<String> classifier, SignatureSpec signatureSpec, Object... tasks)
      Creates a signature artifact for the file returned by the toSign closure.

      The closures will be “evaluated” on demand whenever the value is needed (e.g. at generation time)

      Parameters:
      toSign - A closure that produces a File for the object to sign (non File return values will be used as the path to the file)
      classifier - A closure that produces the classifier to assign to the signature artifact on demand
      signatureSpec - The specification of how the artifact is to be signed
      tasks - The task(s) that will invoke generate() on this signature (optional)
  • Method Details

    • getToSign

      @PathSensitive(NONE) @InputFile public File getToSign()
      The file that is to be signed.
      Returns:
      The file. May be null if unknown at this time.
    • setName

      public void setName(String name)
    • getName

      @Internal public String getName()
      The name of the signature artifact.

      Defaults to the name of the signature file.

      Returns:
      The name. May be null if unknown at this time. FIXME Nullability consistency with superclass.
    • setExtension

      public void setExtension(String extension)
    • getExtension

      @Internal public String getExtension()
      The extension of the signature artifact.

      Defaults to the specified file extension of the signature type.

      Returns:
      The extension. May be null if unknown at this time. FIXME Nullability consistency with superclass.
    • setType

      public void setType(String type)
    • getType

      @Internal public String getType()
      The type of the signature artifact.

      Defaults to the extension of the file to sign plus the extension of the signature type. For example, when signing the file ‘my.zip’ with a signature type with extension ‘sig’, the default type is ‘zip.sig’.

      Returns:
      The type. May be null if the file to sign or signature type are unknown at this time. FIXME Nullability consistency with superclass.
    • setClassifier

      public void setClassifier(String classifier)
    • getClassifier

      @Internal public String getClassifier()
      The classifier of the signature artifact.

      Defaults to the classifier of the source artifact (if signing an artifact) or the given classifier at construction (if given).

      Returns:
      The classifier. May be null if unknown at this time.
    • setDate

      public void setDate(Date date)
    • getDate

      @Internal public Date getDate()
      The date of the signature artifact.

      Defaults to the last modified time of the signature file (if exists)

      Returns:
      The date of the signature. May be null if unknown at this time.
    • getFile

      @OutputFile public File getFile()
      The file for the generated signature, which may not yet exist.

      The file will be placed alongside the file to sign with the extension of the signature type.

      Returns:
      The signature file. May be null if unknown at this time.
      See Also:
    • getSignatory

      @Internal("already tracked as part of the Sign task") public Signatory getSignatory()
      The signatory of this signature file.
      Returns:
      The signatory. May be null if unknown at this time.
    • getSignatureType

      @Internal("already tracked as part of the Sign task") public SignatureType getSignatureType()
      The file representation type of the signature.
      Returns:
      The signature type. May be null if unknown at this time.
    • setSignatureSpec

      public void setSignatureSpec(SignatureSpec signatureSpec)
    • getSignatureSpec

      @Internal public SignatureSpec getSignatureSpec()
    • getBuildDependencies

      @Internal public TaskDependency getBuildDependencies()
      Description copied from interface: Buildable
      Returns a dependency which contains the tasks which build this artifact. All Buildable implementations must ensure that the returned dependency object is live, so that it tracks changes to the dependencies of this buildable.
      Specified by:
      getBuildDependencies in interface Buildable
      Overrides:
      getBuildDependencies in class org.gradle.api.internal.artifacts.publish.AbstractPublishArtifact
      Returns:
      The dependency. Never returns null. Returns an empty dependency when this artifact is not built by any tasks.
    • shouldBePublished

      public boolean shouldBePublished()
    • generate

      public void generate()
      Generates the signature file.

      In order to generate the signature, the file to sign, signatory and signature type must be known (i.e. non null).

      Throws:
      InvalidUserDataException - if the there is insufficient information available to generate the signature.
