The last thing i have problems with is, to compile my Caps with “mvn install”
The Error looks like this:

The project i am compiling is an existing project that i developed on the UR Starter Package. Do i have to change the existing POM file?
I am trying since three days but did not come close to a solution. I’m begging for help

The problems seems to be the fact that maven cannot find the package “org.apache.xmlrpc.client” since it has printed “package org.apache.xmlrpc.client does not exist” and the rest of the error is because of the code that uses this package cannot be compiled due to the package has not been found problem. It might be the setup of maven. Have you found any solution?

Yes, i had to add some external JARs in Eclipse including the mentioned one. Additionally i had to remove one part from my POM file. Now its working almost perfect. The only problem remaining is, that my python daemon does not start automatically when i start the URSIM.

It sounds great! Where in the URCap are you starting your daemon?
Something like this line of code: “daemonService.getDaemon().start();” ?

Yes exactly like that in my InstallationContribution. I copied it from the MyDaemonSwing example.
Is it outdated? It worked on an older Version in the StarterPackage.

For quick test to see if the daemon is running I started the daemon under Open view() or you can also do it when clicking a button.
Beside the example “MyDaemonSwing” you can also look at the example given by Jacob Bom Madsen on his [github](https://github.com/BomMadsen/URCap-getControllerTime/tree/master/com.ur.urcap.sample.getControllerTime/src/main/resources/com/ur/urcap/sample/getControllerTime/impl/daemon).
This link brings you to the python file used in the example. You can see if there is anything different from yours. I also used this file to check whether my code was running by changing my file to this file. If it runs using this file and not with yours, it could be the code in the python file, version of the python etc.
If this does not work - please tell

I downloaded the getControllerTime-Example and tried it via URSIM. Same issue. The XMLRPC-Server doe not start automatically. I have to start it via terminal manually to get the URCaps working properly. It is not an issue with the python file itself. I think my setup of the URSIM Environment is not entirely correct.

REPOST:
Having same issue when building MyDaemonSwing. There was an error on eclipse saying “plugin execution not covered by lifecycle configuration”, I tought it was worked around by setting Eclipse’s preferences \> Maven \> Errorr/Warning and setting plugin from Error to Ignore. The error appers to be solved on eclipse, but when triying to build with mvn install same error on Mojo plugin appears.
SOLUTION, wordked for me: In Eclipse \> Window \> Preferences \> Maven \> Discovery \> Open Catalog \> (search with “MOJO” keyword and install the two m2e connector missings)
I dont overthink about it by now because just want to deploy MyDaemonSwing for testing.

Hi,
I faced same errors few days ago when developing my first urcap with a Daemon which implements a XMLRPC server.
For what it concern the running of the daemon from URSIM I solved running it with sudo privileges
> sudo ./start-ursim.sh
To solve the error :
> package org.apache.xmlrpc.client does not exist
I had to modify my project pom, in the dependency settings the org.apache.xmlrpc must be added, as in the mydaemon swing package.
```
org.apache.xmlrpc
xmlrpc-client
3.1.3.0
org.apache.xmlrpc
xmlrpc-common
3.1.3.0
org.antlr
stringtemplate
org.antlr
antlr-runtime
```
Best Regards
Castelli Pietro

Hi,
Apologies for posting here but I don’t seem to have the option to create new threads. You say you fought to install URSIM - by any chance have you run into this particular problem? Here is my log:
