Hi,

IIRC I removed the exercise because it was outdated. I try to update it tomorrow and re-add it to the training. Best regards, Lars

Hi Lars, thank you very much. I have to say that your training has been instrumental in helping me with my program. Without it, the desire to build my program would not have become a reality.

Hi Kurt,

thanks for the feedback. The new exercise is almost ready. Unfortunately I can only work on it again next Wednesday but I hope I will be able to publish it on this day.

Best regards, Lars

Yes sir! Looking forward to learning more and thank you very much again!

Hi,

I added two exercises, one for the usage of the HttpClient (which could also be used parse the Restful service) and another with the usage of the retrofit library.

I hope this help. Please reopen if something is missing / unclear.

Thanks again for the super fast support! I’ll attempt these trainings in the next few days and let you know if I run into any issues.

Hi Lars, this is my first time using Maven in the target description. So, I may have done something incorrectly. However, I had to add the following to get the code to compile/work inside eclipse

After adding these dependencies, everything is working in eclipse nicely.

Unfortunately when I try to export the project, the Maven build is throwing the following error: mvn clean verify …​

Here is some eclipse info Eclipse SDK Version: 2021-12 (4.22) Build id: I20211124-1800 JavaSE-11

Regards,

Kurt

Here is my target definition for the Maven location <location includeDependencyDepth="infinite" includeDependencyScopes="compile" includeSource="true" missingManifest="generate" type="Maven"> <feature id="maven.dependencies" label="Dependencies from Maven Central" version="1.0.0.qualifier"></feature> <dependencies> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.8.9</version> <type>jar</type> </dependency> <dependency> <groupId>com.squareup.okhttp3</groupId> <artifactId>okhttp</artifactId> <version>4.9.3</version> <type>jar</type> </dependency> <dependency> <groupId>com.squareup.okio</groupId> <artifactId>okio</artifactId> <version>2.8.0</version> <type>jar</type> </dependency> <dependency> <groupId>com.squareup.retrofit2</groupId> <artifactId>converter-gson</artifactId> <version>2.9.0</version> <type>jar</type> </dependency> <dependency> <groupId>com.squareup.retrofit2</groupId> <artifactId>retrofit</artifactId> <version>2.9.0</version> <type>jar</type> </dependency> <dependency> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-stdlib</artifactId> <version>1.4.10</version> <type>jar</type> </dependency> </dependencies> </location>

Sorry for the multiple comments. I was getting a SQL error when trying to save the entire response as one.

Maven build error;

Invalid syntax in target definition C:\Users\kurt\Documents\workspace\karma\target-platform\target-platform.target: Missing child element 'groupId' → [Help 1]

Which Tycho release are you using? The old description used Tycho 2.2.0 which did not support yet the new Maven extension. It has been updated to 2.6.0 which supports also the new Maven elements. See https://learn.vogella.com/exercises/rich-client-platform/exercise-building-eclipse-rcp-applications-with-maven-3chf8

That was the issue. I must have been using the training exercise when I first purchased it and never used the m2e extension until recently.

Anyway, your updated REST training is working for me and now the Tycho build is also working.

Thank you very much!

Feel free to close this ticket.

Thanks for the feedback and great to hear that this is working for you.
