Could not determine java version from '9.0.1'

@to175 In your post (Could not determine java version from '9.0.1') you show a snippet from your gradle/wrapper/gradle-wrapper.properties file:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.3-src.zip

The last line (distributionUrl=https\://services.gradle.org/distributions/gradle-4.3-src.zip) points to the source distribution (note the -src). This distribution cannot be used to run Gradle.
You need to change -src to -bin (or -all) to be able to launch Gradle via the wrapper.
