geowave failed to compile, problem with maven-compiler-plugin?

[tsandio]

Observed error while building- [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project geowave-core-store: Compilation failure [ERROR] /Users/terry/Documents/ods/geowave/core/store/src/main/java/org/locationtech/geowave/core/store/base/BaseDataStoreUtils.java:[836,42] incompatible types: inferred type does not conform to equality constraint(s) [ERROR] inferred: org.locationtech.geowave.core.store.dimension.NumericDimensionField<capture#1 of ?> [ERROR] equality constraints(s): org.locationtech.geowave.core.store.dimension.NumericDimensionField

Possible issue with using newer versions? java -version java version "16.0.2" 2021-07-20 Java(TM) SE Runtime Environment (build 16.0.2+7-67) Java HotSpot(TM) 64-Bit Server VM (build 16.0.2+7-67, mixed mode, sharing)

Had another build error that required changing the version of spotbugs to 4.2.2 Tried changing version of maven-compiler-plugin to 3.8.1 but did not resolve issue.

Thanks for any help

yep, you are right, its an issue with versions. We require java 8.

Noted. I will try and downgrade java and maven versions. Just like to point out that your documentation says, Requires JDK v1.8 or greater at https://locationtech.github.io/geowave/devguide.html#build-python-bindings

Rich,

I am still unable to compile geowave. I am now using Java 8 that came built in with the Mac OS.

java -version

java version "1.8.0_151"

Java(TM) SE Runtime Environment (build 1.8.0_151-b12)

Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)

The problem appears to be Maven related. I have tried

apache-maven-3.2.1 (requires modification to the pom.xml file for https as opposed to http)

apache-maven-3.3.9

apache-maven-3.5.4

apache-maven-3.6.3

apache-maven-3.8.2

For example:

mvn --version

Apache Maven 3.8.2 (ea98e05a04480131370aa0c110b8c54cf726c06f)

Maven home: /usr/local/opt/apache-maven-3.8.2

Java version: 1.8.0_151, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home/jre

Default locale: en_US, platform encoding: UTF-8

OS name: "mac os x", version: "10.16", arch: "x86_64", family: "mac"

I continue to get this error:

mvn clean install

I have tried to test the pom.xml:
