android启动问题。不支持的班级文件主要版本57

15

我已经按照mac android入门，但是当我运行android时，它失败并出现以下错误。我试图在线找到答案，但似乎找不到解决方案。香港专业教育学院确保我在机器上安装了正确的Java JDK8，但即时通讯仍然收到此错误。任何意见是极大的赞赏！

我也遇到相同的错误，并显示以下消息Could not compile settings file '/Users/.../android/settings.gradle'.

跑步时我遇到同样的问题gradle build。根据Google和github的搜索。我发现gradle当前版本（5.xx）不支持jdk13。最后，6.x版本支持它，但尚未发布，因此我必须将jdk版本降级为12.x。

将Java降级到12 https://www.jverdeyen.be/mac/downgrade-brew-cask-application/

brew cask uninstall adoptopenjdk # uninstall jdk version 13.x
brew cask install https://raw.githubusercontent.com/caskroom/homebrew-cask/025e5b6c3ad66ac2a2da75abb91d109d68dd4f6d/Casks/adoptopenjdk.rb

我从Java 13降级到一个较低的版本，它可以正常工作！

这是因为您的JDK版本不支持您的项目的Gradle版本。jdk-13不支持Gradle 5。最好的解决方案是在gradle-wrapper.properties中更改gradle版本。您可以设置晚于6的任何gradle版本。

要么

转到（在Mac上）“首选项”>“构建，执行，部署”>“渐变”

（Windows）文件>设置>构建，执行，部署> Gradle

然后在Gradle部分下，您可以选择Gradle和Java，如下图所示在此处输入图片说明

您也可以单独安装gradle并使用指定的路径。但是，我建议您将gradle-wrapper.properties文件和Gradle JVM用于内部JDK或Project JVM。这样，您不必卸载JDK 13并安装降级的JDK11或JDK12

如果在Android Studio中找不到此选项，请降级JDK或使用第一个选项。

为了解决这个错误，我进入了android / gradle / wrapper / gradle-wrapper.properties文件，并将distributionUrl修改为gradle-5.5到gradle-6.0。由于某种原因，它不能识别6.2发行版，即使这是我当前使用的gradle版本。我认为这应该与版本相对应，但显然不符合。

之前：distributionUrl = https：//services.gradle.org/distributions/gradle-5.5-all.zip

之后：distributionUrl = https：//services.gradle.org/distributions/gradle-6.0-all.zip

让我知道这是否对您有用。

谢谢！这是我的问题。使用ignite-cli和我的React Native项目。

如果您不想降级JDK发行版，则可以使用gradle包装器的快照之一，这似乎对很多人都有用（对我来说也是如此）

解决方案的来源：https : //github.com/gradle/gradle/issues/8681#issuecomment-524039994

要使用快照，请选择以下文件之一：https : //services.gradle.org/distributions-snapshots/，转到您的PROJECT_ROOT/gradle/wrapper/gradle-wrapper.properties文件，然后将zip文件地址作为的值distributibutionUrl

不错，这允许您同时使用Java 13和Gradle ：)一个小的补充：gradle 6.0的RC发行版，应该比旧的快照更稳定：services.gradle.org/distributions/gradle-6.0 -rc-1-bin.zip

我从AdoptOpenJDK 13升级到14，现在我的Android项目已成功构建。
