ContributionsMost RecentMost LikesSolutionsRe: A required class was missing while executing com.snaplogic.tools:snappack-installer:4.9.0.M1:generate-schema: javax/xml/soap/SOAPException Finally got it to build. I think my issue was due to cross-corruption between Java 8 and Java 10 in the .m2 directory. After wiping out the entire .m2 directory and reinstalling all dependencies, it is now building correctly.
