Oracle Maven Sync Plugin Installation : Return code is: 401, ReasonPhrase: Unauthorized

While trying to install the maven-sync-plugin to a centralized repository like Archiva/Artifactory

sometimes an authorization error happens as follows

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:
deploy-file (default-cli) on project standalone-pom: Failed to deploy artifacts:
 Could not transfer artifact com.oracle.maven:oracle-maven-sync:jar:12.1.3-0-0 f
rom/to remote-repository (http://localhost:8091/artifactory/internal): Failed to

le-maven-sync/12.1.3-0-0/oracle-maven-sync-12.1.3-0-0.jar. Return code is: 401,
ReasonPhrase: Unauthorized. -> [Help 1]

This can be resolved by doing the following steps

1) Create a new user called demouser in the Archiva/Artifactory
2) Give the permissions to the user to the desired repositories
3) encrypt the password using the command mvn -ep <password>

4)Use the encrypted password in the settings.xml, as shown below

<?xml version="1.0" encoding="UTF-8"?>
<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.1.0"

  <password>{y2ZZOfE4lLkH78iLLX9xLQjL2/Rkoocq/Yq5HrACJdM=}</password>
    </server>
  </servers>
</settings>

6)Also create a master password using mvn -emp <masterpassword>

7)Create a settings-security.xml with the encrypted master password as shown below
 Note: replace your master password inside the <master> tag

<settingsSecurity>
  <master>{nng7rwwwwKMHM+yJE3201WFQ1WlzYUfgoZGxW2mIcTc=}</master>
</settingsSecurity>

8)Place this  settings.xml and settings-security.xml  under <userhome>/.m2 directory

9) Now execute the install command as follows.

open the command prompt

Navigate to <ORACLE_HOME>\oracle_common\plugins\maven\com\oracle\maven\oracle-maven-sync\12.1.3

The execute the following command at the prompt :

mvn deploy:deploy-file -DpomFile=oracle-mave
n-sync-12.1.3.pom -Dfile=oracle-maven-sync-12.1.3.jar -Durl=http://localhost:8091/artifactory/internal -DrepositoryId=internal

Note : Ensure the  -DrepositoryId is spelled as given in the above command(case sensitive).  Don't use  -DRepositoryId

10)Once this command runs successfully, then execute the push goal as shown below

mvn com.oracle.maven:oracle-maven-sync:push
-DoracleHome=C:\installed\Oracle\Middleware12C\Oracle_Home  -DserverId=internal

This too will now run successfully and your repository will now have all the necessary artifacts installed .

11) To validate your installation run the following command. This will show all the availble goals which you can now use

mvn help:describe -DgroupId=com.oracle.soa.plugin -DartifactId=oracle-soa-plugin -Dversion=12.1.3-0-0

The result will be as follows
====================================
This plugin has 6 goals:

oracle-soa:compile
  Description: Compiles the composite. Note that 'compiling' a composite does
    not actually produce any new files, it is really a 'validation' and
    produces only output messages.

oracle-soa:deploy
  Description: To deploy a SOA composite (supports all formats SAR, MAR,
    etc.)

oracle-soa:help
  Description: Display help information on oracle-soa-plugin.
    Call mvn oracle-soa:help -Ddetail=true -Dgoal=<goal-name> to display
    parameter details.

oracle-soa:sar
  Description: Packages the composite into a SAR.

oracle-soa:test
  Description: To execute SCA Test Suites.

oracle-soa:undeploy
