InternetDomainName.findSuffixOfType() in junit test returns java.lang.NoSuchFieldError: EXACT

I’m using guava 24.1-jre and jdk 1.8.0.162

InternetDomainName.from("google.com");

causes

java.lang.NoSuchFieldError: EXACT

	at com.google.common.net.InternetDomainName.findSuffixOfType(InternetDomainName.java:172)
	at com.google.common.net.InternetDomainName.<init>(InternetDomainName.java:153)
	at com.google.common.net.InternetDomainName.from(InternetDomainName.java:212)
	at com.dnb.vici.formfill.common.UtilFunctions.getCustomerAndDomainId(UtilFunctions.java:73)
	at com.dnb.vici.formfill.ut.UtilFunctionsTest.getCustomerAndDomainIdTest(UtilFunctionsTest.java:73)

It’s failing on InternetDomainName.java Line #172 and this old storm issue returns a very similar error.

In IntelliJ when I evaluate the expression, it returns false as expected but running through the code will throw the exception and it only happens during a unit test… Why does this happen?

That’s awesome, thank you @Stephan202!

@nitrocode I’d add the aforementioned checks to your build by default; they could be part of a shared company POM. Others I recommend:

• The maven-enforcer-plugin’s dependencyConvergence.
• The maven-dependency-plugin’s various analyze* goals.

At Picnic we use a parent which has these and other checks; it ensures that each of our projects has a well-behaved build. (Open-sourcing (a variation of) this pom.xml is on my TODO list, but realistically it’s a few months out.)

Edit: actually, most of that parent pom was copied over and open-sourced here. The relevant tidbits are spread across the pluginManagement section section and the build-checks profile.
