We are trying to set up SonarCloud with CircleCI for one of our iOS projects on a GitHub repository, but encountering some hard-to-resolve errors. These are the steps we have taken so far: - Since we are using CircleCI, naturally we chose to follow the instructions for analyzing with CircleCI. - We have created a SonarCloud context and added a `SONAR_TOKEN` environment variable. - Since our project is in Swift, we selected “Other” to best describe our build. - We have allowed our organization to use third-party orbs. - Since the orb doesn’t support macOS, we chose to use the [pre-built CircleCI base image](https://circleci.com/docs/2.0/circleci-images/#circleci-base-image) Here is what was added to our existing `.circleci/config.yml` (stripped out our other jobs): ```auto version: 2.1 orbs: sonarcloud: sonarsource/sonarcloud@1.0.2 jobs: sonar-cloud-orb: docker: - image: cimg/base:2021.04 steps: - checkout - sonarcloud/scan workflows: version: 2 build-and-deploy: jobs: - sonar-cloud-orb: context: SonarCloud filters: branches: only: develop ``` And when we push to develop branch we get the following error message ( **stripped out most of the stacktrace to keep within character limits** ): ```auto INFO: ------------------------------------------------------------------------ INFO: EXECUTION FAILURE INFO: ------------------------------------------------------------------------ INFO: Total time: 47.388s INFO: Final Memory: 55M/194M INFO: ------------------------------------------------------------------------ ERROR: Error during SonarQube Scanner execution java.lang.StackOverflowError at java.base/java.util.stream.AbstractPipeline.wrapSink(Unknown Source) [...] at java.base/java.util.Spliterators$IteratorSpliterator.tryAdvance(Unknown Source) ERROR: ERROR: Re-run SonarQube Scanner using the -X switch to enable full debug logging. Exited with code exit status 1 CircleCI received exit code 1 ``` Which doesn’t say that much to us what went wrong. Not sure how to use the -X switch when using the orb but we did also try to manually download and run `sonar-scanner` on the Linux image just so we could add the -X switch and get verbose logging. Alas, the same error was thrown without any useful logs or hints as to what is going on. Any help with moving forward on this would be very appreciated as we are currently at a loss on how to fix it. Please let me know if any more information is needed to be able to investigate this. ---

Hi @henrikforsberg Seeing the ```auto INFO: Final Memory: 55M/194M ``` It looks like the JVM runing the scan doesn’t have that much of memory available. Can you try to increase the heap size ? Mickaël ---

Unfortunately I have no idea how to do that but I definitely want to give it a try. Could you please give me a hint on how to proceed? ---

I’m not quite sure of the outcome, but maybe try this : ```auto jobs: sonar-cloud-orb: docker: - image: cimg/base:2021.04 environment: SONAR_SCANNER_OPTS: -Xmx512m steps: - checkout - sonarcloud/scan ``` ---

I immediately tried it. Sadly, that gave us basically the same output as before: ```auto INFO: ------------------------------------------------------------------------ INFO: EXECUTION FAILURE INFO: ------------------------------------------------------------------------ INFO: Total time: 40.500s INFO: Final Memory: 55M/194M INFO: ------------------------------------------------------------------------ ERROR: Error during SonarQube Scanner execution java.lang.StackOverflowError at java.base/java.util.stream.StreamOpFlag.fromCharacteristics(Unknown Source) ``` ---

For @mickaelcaro and anyone else seeing this: We realized this was actually a stackoverflow error so we ended up adding the following to the environment to increase the stack size: `SONAR_SCANNER_OPTS: -Xss16m -Xmx1g` Seems to have done the trick. ---
