gradlew似乎在Java 10上仍然有问题（请参阅下文）。
我删除gradlew /，使用4.9做gradle包装，然后尝试gradlew -v，我得到一些警告，并且：无法从'10'确定Java版本。
有人解决吗？
编辑：gradle-wrapper属性说：
D:\ray\dev\conradapps\rabbit\gradle\wrapper>cat gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
但是我 just 用4.9创建了它，所以我很困惑：（
edit2：@Aris建议查看构建文件，果然，我在其中有一个“任务包装器（类型：包装器）{gradleVersion ='2.14'}”。
edit3：从构建文件中删除包装器任务，然后通过执行gradle包装器创建另一个任务就可以了！

即使您将本地Gradle发行版升级到新版本，gradle包装器使用的版本仍然非常旧，这意味着它不支持新的Java版本。您的gradlew.properties文件和build.gradle包装器任务的版本可以证明这一点。
修复gradle包装器任务的gradle版本应该可以解决此问题。然后，您应该能够重新运行包装器任务并创建正确的包装器。
