Hi all, I followed the instructions here https://www.openhab.org/docs/developer/ide/eclipse.html to configure my eclipse IDE. I imported all openHAB working set except for Zigbee and ZWave binding. However after it finishes building automatically, many errors come out and here is the screenshot. Notice that here I only open openhab-core and Infrasturce, and leave OH2 addons and Web UIs close.
I think the problem lies mainly in org.openhab.core.model, because it lets other bundles like boot not be built. I have tried clean and re-build, but it does not work. Could anyone help me out?
I have solved this issue. I updated all bundles. But after that there are 800 errors, most with type Java Problem, come out!!! Here is the screenshot (part of):
Java VM: OpenJDK 64-Bit Server VM (25.232-b18 mixed mode bsd-amd64 compressed oops)
Problematic frame:
C [libzip.dylib+0x2e92] newEntry+0x154
Failed to write core dump. Core dumps have been disabled. To enable core dumping, try “ulimit -c unlimited” before starting Java again
Everything installed as expected, but than I got a “Build failed” error message. After that I tried to run your recommended
but that produced even more errors.
My question / problem
Could you please help me to find a solution? Do you have any idea where I maybee missed something?
Thank you in advance for your help!
My goal and my system settings
My goal is to start creating my own binding.
I’m on a Mac (OSX 10.14.6)
Commandline: Java version
java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_252-b09)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.252-b09, mixed mode)
Ecplipse version
Eclipse IDE for Java Developers
Version: Oxygen.3a Release (4.7.3a)
Build id: 20180405-1200
A step by step explanation:
I installed Eclipse with the recommended manual (see link above)
I selected all options except the options for Zigbee and ZWave
Everything was downloaded successfully
Then the build faild with some error messages (see attached file “Error_Build.txt”)
Then I opened the file “openhab-distro/launch/ModelGen.launch” in eclipse and pressed the green run button in Eclipse and this produced some error messages (see attached file “Error_ModelGen.launch.txt”)
This thread missed one question I didn’t ask. Do you want to develop for core? In other words if you want to develop a binding you only should select development and openhab-addons. Don’t select core.
Thank you for pointing out the question! Regarding the main headline of this thread, would you recomand me to open a new thread or should we continue in this one?
I uninstalled everything regarding Eclipse and the selections during the Eclipse installer process. Then I re-run it and only selected development and openhab-addons. Unfortunately the build failed again. Here is the output of the build error message:
Errors occurred during the build.

There can be several causes. It should work under normal circumstances. As I don’t know what versions you have, see this stackoverflow question with different suggestions:
The stackoverflow question has several possible solutions, part of those are related to versions. So it might be version related, but not necessarily. It would just makes it more guessing that I don’t know the versions and some answers are related to specific versions of maven, therefor I couldn’t give a specific answer. I think the stackoverflow answers should cover most cases and will very likely give you the answer. For openHAB development on 2.5 make sure you use Java 8.
Hi Hilbrand, I wanna ask what the normal routine if I want to develop the core? As far as I am concerned, I just build the core locally, and in the provided app.bndrun, I just set the core to my local build. Am I correct? Or should I use that Jenkins?
You can develop on core just like a binding. Just import the projects of core you want to develop on. If you want to develop for core make sure you develop on the master branch, which is for openHAB 3. And use Java 11. Because openHAB 3 requires Java 11. Jenkins is for the cloud build, not really useful for development.
