I tried nmpInstall enabled = false, but it didn't help.

A problem was found with the configuration of task ':contracts:npmInstall' (type 'NpmInstallTask').
  - Type 'com.github.gradle.node.npm.task.NpmInstallTask' property 'packageJsonFile' doesn't have a configured value.

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.internal.execution.WorkValidationException: A problem was found with the configuration of task ':contracts:npmInstall' (type 'NpmInstallTask').
  - Type 'com.github.gradle.node.npm.task.NpmInstallTask' property 'packageJsonFile' doesn't have a configured value.
    
    Reason: This property isn't marked as optional and no value has been configured.
    
    Possible solutions:
      1. Assign a value to 'packageJsonFile'.
      2. Mark property 'packageJsonFile' as optional.

Solved this by adding a solidity file under src/main/solidity/.

This error may caused by missing package.json under build/ dir when working with gradle-node-plugin, package.json is generated in gradle task 'resolveSolidity'. I guess no solidity file -> nothing to do in 'resolveSolidity' -> no package.json -> gradle-node-plugin error. (Maybe it's better to skip it in this situation.)
