Introduction : A lot of participants had trouble (including myself) doing the initial setup as the installation step was referred to another course and there were quite some points where troubleshooting was needed. This documents aims at smoothening out those rough edges for people who are not too savvy with the mentioned tools yet. Also a lot of screenshots make it much easy to understand.

Date created : 14.09.2016

Download JDK and set JAVA_HOME and PATH environment variables.

Download Link
JDK 7 (64 bit) http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-

Test that the environment variables JAVA_HOME and PATH are set properly by echo command on CMD.

Please note:

JAVA_HOME = Java main folder

PATH = path till bin inside Java main folder

echo %JAVA_HOME%

echo %PATH%

Capture.PNG

Test that Java is available on CMD

Download Eclipse Mars/Neon

Download Link
Eclipse IDE for Java EE Developers (64 bit) https://eclipse.org/downloads/eclipse-packages/

In my case the latest Eclipse Neon was giving trouble so I just switched to older Eclipse Mars that I already had.

Run Eclipse, choose workspace location. In my case I kept my workspace within my Eclipse folder in case I use more than one Eclipse on my system.

Eclipse Plugins Link

SAP Hana Cloud Paltform Tools &

SAP HANA Tools

For Eclipse Neon (4.6), use https://tools.hana.ondemand.com/neon

For Eclipse Mars (4.5), use https://tools.hana.ondemand.com/mars

Capture.PNG

Install the plugins. This takes a couple of minutes.

Capture.PNG

Eclipse Plugin Link

EGit

Information Page :

http://www.eclipse.org/egit/download/

Plugin Link

http://download.eclipse.org/egit/updates

Same process as for the last two plugins. This takes a couple of minutes.

Capture.PNG

We need Maven too but we do not need to install the plugin as it comes preinstalled with Eclipse for J2EE.

GIT Configuration

Capture.PNG

Maven User Settings

Capture.PNG

The settings.xml file has to be created the first time under the .m2 directory.

Remove the comments when copying xml.

You can remove the proxies tag and its contents if you are not using a proxy.

Or you can write false in the <active> tag.

//Start of settings.xml

<settings xmlns=http://maven.apache.org/SETTINGS/1.0.0

  xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance

  xsi:schemaLocation=http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd>

   <localRepository>${user.home}/.m2/repository</localRepository>

   <profiles>

        <profile>

             <id>development</id>

             <activation>

                  <activeByDefault>true</activeByDefault>

             </activation>

             <properties>

             </properties>

        </profile>

   </profiles>

   <proxies>

        <proxy>

             <active>true</active>

             <protocol>http</protocol>

             <host>proxy</host>

             <port>8080</port>

        </proxy>

   </proxies>

   </settings>

//End of settings.xml

Set JDK in Eclipse. This steps avoids problem with Maven build process later.

NOTE : This step is important. If not done, your maven build will fail in later steps.

Tools Link
HANA Cloud Paltform SDK https://tools.hana.ondemand.com/#cloud

Download the following files.

Capture.PNG

And setup these as Server Runtime Environments

Capture.PNG

Clone the GIT repository in the EGit perspective in Eclipse.

GIT Repository Link to GIT Repository
ESPM V2 https://github.com/SAP/cloud-espm-V2

Capture.PNG

Capture.PNG

Copy (CTRL + C) the ESPM Git Repository Path (*) above and right click in the Git perspective

Capture.PNG

Just click Next

Capture.PNG

Next again, no rocket science involved so far. Just check that all branches are selected.

Capture.PNG

Finish the wizard. This takes a couple of minutes.

Capture.PNG

AHOY ! Repository cloned. You can see the branches too as we selected in the wizard.

Capture.PNG

Import existing Maven project in J2EE Perspective

Capture.PNG

Capture.PNG

Select the ESPM project in Git folder hierarchy and finish the wizard. This takes a couple of minutes.
It should be something like :

C:\Users\<username>\git\cloud-espm-V2

Capture.PNG

Capture.PNG

Select ESPM main project -> Right click -> Maven -> Maven Update Project

Capture.PNG

Capture.PNG

Select ESPM main project -> Right click -> Run As -> Maven build…

Capture.PNG

Enter “clean install” in Goals and then Run. This takes a couple of minutes.

Capture.PNG

This should ideally result into 3 SUCCESS messages

Capture.PNG

Right click on Project Explorer and refresh and you would see that a new deploy folder is created with a .war file inside post build process.

Capture.PNG

We will deploy this .war file in the Hana Cloud Platform Cockpit in the Java Applications area

For some reason SCN is not allowing me to add more screenshots so I will have to continue in another document.
