gradle 4.9 - gradlew 和 java 10 仍然得到：无法确定来自 '10' 的 java 版本
gradle 4.9 - gradlew and java 10 still get: Could not determine java version from '10'
gradlew 似乎仍然存在 java 10 的问题（请参阅下文）。
我删除 gradlew/，用 4.9 做一个 gradle 包装器，然后尝试 gradlew -v，我收到一些警告并且：无法确定 java 来自“10”的版本。
有人有解决方法吗？
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
但是我只是用4.9创建的，所以我很困惑:(
edit2：@Aris 建议查看构建文件，果然，我在那里有一个 "task wrapper(type: Wrapper) { gradleVersion = '2.14' }"。
edit3：从构建文件中删除包装器任务并通过执行 gradle 包装器创建另一个工作正常！

即使您将本地 Gradle 发行版升级到新版本，您的 gradle 包装器使用的版本仍然很旧，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 包装任务的 gradle 版本应该可以解决这个问题。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。
