Maven plugin does not decrypt encrypted proxy password

[shmyer]

I am using an encrypted password for proxy authentication in my settings.xml file, which is not working with the ossindex-maven-plugin (See https://maven.apache.org/guides/mini/guide-encryption.html#how-to-encrypt-server-passwords).

It seems like the plugin does not decrypt my password and just uses the encrypted password when providing the "Proxy-Authorization" header. This causes our proxy to deny the request with a 407 Proxy Authentication Required response.
