Benjamin Bentmann closed MNG-4384.
----------------------------------

       Resolution: Won't Fix
    Fix Version/s:     (was: Issues to be reviewed for 3.x)
         Assignee: Benjamin Bentmann

Going forward, I would like plugins to eventually use {{[o.a.m.s.crypto.SettingsDecrypter|http://maven.apache.org/ref/3.0.2/maven-settings-builder/apidocs/org/apache/maven/settings/crypto/SettingsDecrypter.html]}}. In the meantime, this issue can be worked around by depending on {{plexus-sec-dispatcher}} in compile scope and adding the following {{src/main/resources/META-INF/components.xml}} to a plugin:
{code:xml}
<component-set>
  <components>
    <component>
      <role>org.sonatype.plexus.components.sec.dispatcher.SecDispatcher</role>
      <role-hint>mng-4384</role-hint>
      <implementation>org.sonatype.plexus.components.sec.dispatcher.DefaultSecDispatcher</implementation>
      <requirements>
        <requirement>
          <role>org.sonatype.plexus.components.cipher.PlexusCipher</role>
          <role-hint>mng-4384</role-hint>
          <field-name>_cipher</field-name>
        </requirement>
      </requirements>
      <configuration>
        <_configuration-file>~/.m2/settings-security.xml</_configuration-file>
      </configuration>
    </component>
    <component>
      <role>org.sonatype.plexus.components.cipher.PlexusCipher</role>
      <role-hint>mng-4384</role-hint>
      <implementation>org.sonatype.plexus.components.cipher.DefaultPlexusCipher</implementation>
    </component>
  </components>
</component-set>
{code}
and in the mojo inject the component via
{code:java}
/** @component role-hint="mng-4384" */
private SecDispatcher secDispatcher;
{code}
Note the role hints used here to avoid problematic clashes with the component instances from Maven core.
