Dear colleagues, as recommended by rOpenSci (see https://ropensci.org/technotes/2020/11/19/moving-away-travis/) , I am moving to GitHub Actions for the CI for my R packages.
My test case is the “bignlp” package I currently develop (https://github.com/https://github.com/PolMine/bignlpPolMine/bignlp). It is an interface to use the CoreNLP tools which are written in Java. (To explain: Unlike other existing packages that interface to CoreNLP, my intent is to make full use of Java multithreading.) Having used `usethis::use_github_action_check_full(), CI works almost out of the box on the Ubuntu and macOS test environments. But I have a problem to ensure that rJava can find Java. The error I see (Windows, both architectures): Error: Error: R CMD check found ERRORs Execution halted .onLoad failed in loadNamespace() for 'rJava', details: call: inDL(x, as.logical(local), as.logical(now), ...) error: unable to load shared object 'D:/a/_temp/Library/rJava/libs/i386/rJava.dll': LoadLibrary failure: %1 is not a valid Win32 application. (For the full log, see: https://github.com/PolMine/bignlp/runs/1749892186) My first take was to add a step that would make sure that Java is present to .github/workflows/R-CMD-check.yaml: - name: Install Java uses: actions/setup-java@v1 with: java-version: '8' java-package: jdk But that only breaks things CI on Linux without having any change on Windows. I have consulted the manual ‘GitHub Actions with R’ (https://ropenscilabs.github.io/actions_sandbox/), but it does not address Java issues. I tried to find some R package on GitHub that would have rJava as a dependency and that uses GitHub Actions for CI – without success. This is why I’d like to query your experience: How I can make GitHub Actions work on Windows for the scenario of a package that depends on Java/rJava. Many thanks in advance!
