cucumber-android not working because Android is missing javax.xml.stream.*

👓 What did you see?

Hi

During compilation I faced R8 error that javax.xml.stream.* are missing:

ERROR: R8: Missing class javax.xml.stream.XMLOutputFactory (referenced from: void io.cucumber.junitxmlformatter.XmlReportWriter.writeXmlReport(java.io.Writer))
Missing class javax.xml.stream.XMLStreamWriter (referenced from: javax.xml.stream.XMLStreamWriter io.cucumber.junitxmlformatter.EscapingXmlStreamWriter.writer and 12 other contexts)

If I suppress the error with

-dontwarn javax.xml.stream.XMLOutputFactory
-dontwarn javax.xml.stream.XMLStreamWriter

I see runtime error

Looking through SO I found a workaround to add 16 years old library:

androidTestImplementation "javax.xml.stream:stax-api:1.0-2"

which help a little bit, but still the new error:

I believe this one can be fixed with such approach FasterXML/jackson-dataformat-xml#583

✅ What did you expect to see?

Success compilation and no issues runtime

📦 Which tool/library version are you using?

cucumber-android 7.14.0
Android API 29
JDK 17

🔬 How could we reproduce it?

No response

📚 Any additional context?

I don't immediately see how FasterXML/jackson-dataformat-xml#583 would fix the issue. The PR changes .newFactory() to .newInstance() which is already used here. It also looks like there may be something else going on. The error message you got doesn't quite match the one from FasterXML, but rather alipov/ews-android-api#8.

I also don't have anything setup for Android so I can't test or verify anything. But if you can provide a pull request I'd be happy to accept it.

@mpkorstanje , my bad. Thanks for pointing it out.. This solved the problem:

androidTestImplementation 'com.fasterxml:aalto-xml:1.3.3'
