I installed gradle manually ( https://gradle.org/install/).
Now I want to install gradlew ( https://docs.gradle.org/4.10.2/userguide/gradle_wrapper.html).
But then I get this error in the commandline:
**BUILD FAILED** in 0s barry:~ macbookprobartvr$ sudo gradle wrapper **> Task :wrapper** FAILED FAILURE: Build failed with an exception. * What went wrong: Some problems were found with the configuration of task ':wrapper'. > Cannot write to file '/opt/gradle/gradle-5.0-rc-3/bin/gradle/wrapper/gradle-wrapper.jar' specified for property 'jarFile', as ancestor '/opt/gradle/gradle-5.0-rc-3/bin/gradle' is not a directory. > Cannot write to file '/opt/gradle/gradle-5.0-rc-3/bin/gradle/wrapper/gradle-wrapper.properties' specified for property 'propertiesFile', as ancestor '/opt/gradle/gradle-5.0-rc-3/bin/gradle' is not a directory.
Is the documentation wrong?
