Hello,
I’m trying to run openems on a Raspberry pi 4 but I have a run error.
! Failed to start bundle com.google.guava.failureaccess-1.0.1, exception Could not resolve module: com.google.guava.failureaccess [39]
Unresolved requirement: Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=1.7))"
I have this error when i’m running on linux desktop which has the openJDK 11 providing jre 1.8.
when I build it from linux I have the same issue.
What can I do?
Hi Siden,
this might indeed be related to JDK 11 - I believe I have seen this issue before. Can you try in Eclipse IDE if “Resolve” works for “EdgeApp.bndrun”.
Alternatively use the following commands in the command line:
gradlew build -x test
gradlew resolve.EdgeApp
gradlew buildEdge
This will generate a jar-file “openems-edge.jar” in the “build” directory. Try again with this file please.
Regards,
Stefan
Hello,
resolve is not working

I’ve just teste on my raspberry pi but I did not installed eclipse on it so I direcly teste the gradlew commands
The two first commands works fine but when I’m running ./gradlew buildEdge i have the following message
> Task :updateVersion FAILED
FAILURE: Build failed with an exception.
* Where:
Build file '/home/pi/EMS/openems/build.gradle' line: 29
* What went wrong:
Execution failed for task ':updateVersion'.
> Could not find matching constructor for: java.io.File(java.io.File)Hello,
I could finally compile the edge.jar file by replacing the line 29 of build.gradle file from
def openemsConstantsFile = new File(openemsConstantsFilePath)
to
def openemsConstantsFile = new openemsConstantsFilePath
But the .jar file generated gives exactly the same error.
The I installed the java jre 8 on the raspberry and it worked directly
Ok, thanks for digging into this problem. So there seems to be an incompatibility with OpenJDK 11. I opened an issue for that on Github: https://github.com/OpenEMS/openems/issues/655
Please don’t hesitate to get in touch if you have further problems.

Stefan
In my experience, OpenJDK 11 is very often incompatible with projects developed with Oracle JDK 1.8, and should generally be avoided if possible. This is an upstream issue, in my humble opinion.
Thanks Kyle, good to know. I’d still try to keep compatibility with all Java versions from version 8 - but this one does indeed not have a very high priority for me right now.
Small addition for everyone who struggles to run the openems jar and is not an installation expert:
I tried to run Edge on a RaspberryPi4 too (no eclipse or anything) and couldn’t start properly without getting 100+ unresolved requirements exceptions, even though Java-8 was installed.
Only installing java-8 (= java-1.8.0) is not enough. You need to choose it as your active version.
Getting Oracle JDK is not necessary btw. OpenJDK does just fine, just not on version 11 for whatever reason (as pointed out above).
Use
sudo update-alternatives --config java
to list your installed java versions and switch to your desired one.
Choosing java-8-openjdk did the job for me.
