===== Nexus =====

Nexus is a repository which is able to manage artifacts (jar files) for java, so that it can resolve its dependencies.

=== Deploy to Nexus ===

The user have to be authorized:
== Paßwortdatei anlegen ==
XML-Datei C:\Users[KUERZEL]\.m2\settings-security.xml anlegen mit folgendem Inhalt

<code>
<?xml version="1.0" encoding="WINDOWS-1250"?>
<settingsSecurity>
    <master>MASTERPASSWORD_HERE</master>  <!-- 123 -->
</settingsSecurity>
</code>

Diese Datei nimmt das Master-Paßwort auf, das im nächsten Schritt erzeugt wird.

== Passwörter anlegen==
Eigenes Master-Paßwort wählen
mvn --encrypt-master-password your_master_password
Erzeugtes verschlüsseltes Master-Paßwort in settings-security einfügen. Die {} sind Teil des Paßworts.
Benutzerpaßwort (IVU-Domänenpaßwort) ebenfalls verschlüsseln
mvn --encrypt-password your_password
Abschnitt <servers> in settings.xml suchen
Es existieren darin zwei Tags <server>, einer für Snapshots und einer für Releases
Username darin auf den IVU-Login-Benutzer setzen
Password auf das gerade verschlüsselte IVU-Login-Paßwort setzen

</code>

<code>
mvn deploy:deploy-file -Dfile=android-4.1.2_r1.jar -DgroupId=android -DartifactId=android -Dversion=4.1.2_r1 -Dpackaging=jar -DrepositoryId=de.ivu.pto.p31.releases -Durl=http://ac-maven-build/nexus/content/repositories/releases/
</code>



==== Artifacts ====
The artifacts available for deployment can be found here:

|android|http://grepcode.com/snapshot/repo1.maven.org/maven2/com.jayway.maven.plugins.android.generation2/android-maven-plugin/4.1.2|



==== Install Nexus plugins ====
Here are the details: https://books.sonatype.com/nexus-book/reference/install-additional-plugins.html

The structure of the nexus plugins looks as following:
<code>
 [nexus-name-plugin-version]
  dependencies  
  META-INF  
  nexus-name-plugin-version.jar
</code>

To install plugins you have to unpack into the plugins into the folder **[SONATYPE-WORK-FOLDER]/nexus/plugin-repository** 

Example of **SONATYPE-WORK-FOLDER** 
<code>
/usr/share/tomcat7/sonatype-work/nexus/plugin-repository 
</code>



==== P2 Update Sites ====
P2 Update Sites may be hosted on Nexus, by installing the maven Unzip Plugin: [[ http://repo1.maven.apache.org/maven2/org/eclipse/tycho/nexus/unzip-repository-plugin/0.14.0/unzip-repository-plugin-0.14.0-bundle.zip| it is hosted here]] 

|org.eclipse.tycho.nexus 0.14.0 | [[http://repo1.maven.apache.org/maven2/org/eclipse/tycho/nexus/unzip-repository-plugin/0.14.0/unzip-repository-plugin-0.14.0-bundle.zip|Maven2 repository]] |
|org.sonatype.nexus 1-3 | [[http://repo1.maven.org/maven2/org/sonatype/nexus/plugins/nexus-unpack-plugin/|Maven2 repository]] |

  * deploy the update site to Nexus in a zip file
  * Maven may unzip the file on the fly and provide a URL

The details about installation and configuration of the Nexus Unzip Plugin are here:
https://wiki.eclipse.org/Tycho/Nexus_Unzip_Plugin

==== Latest artefact from maven-repository ====
Details here: https://support.sonatype.com/entries/23674267-How-can-I-retrieve-a-snapshot-if-I-don-t-know-the-exact-filename-

<code>
wget "http://repository.sonatype.org/service/local/artifact/maven/content?r=snapshots&g=org.sonatype.nexus&a=nexus-utils&v=LATEST" --content-disposition

==== using curl====

Workin on a **raw** repository "rawtest"

<code>
# upload
curl.exe --fail -u admin:admin123 --upload-file ./Hello_Iam_an_artifact.txt.zip http://localhost:32553/repository/rawtest/ 

# delete via curl on Nexus
# DELETING FOLDERS DONT WORK IN NEXUS3

</code>


==== Upload using maven ====

To repos

==== Powershell script to import filesructure into the Nexus====
<code>
function GetFiles($path = $pwd, [string[]]$exclude) 
{ 
    foreach ($item in Get-ChildItem $path)
    {
        if ($exclude | Where {$item -like $_}) { continue }
