如何修复"flutter doctor --android-licenses"Java错误?没有Android Studio [英] How to fix "flutter doctor --android-licenses" java error? Without android studio

问题描述

当我尝试使用命令 flutter doctor --android-licenses 接受android许可证时，会抛出Java错误.

When I try to accept android licenses using command flutter doctor --android-licenses a java error is thrown.

这是Java错误:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema
        at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>(SchemaModule.java:156)

这是我的 flutter doctor -v 的输出:

如何解决上述Java错误?

How can I solve above java error?

注意:我想在不使用Android Studio的情况下解决此问题.

Note: I want to solve this problem without using Android Studio.

推荐答案

之所以会出现此问题，是因为运行 flutter doctor --android-licenses 时，它隐式地运行仅适用于sdk的工具 JDK 8 (afaik，如果我错了，请纠正我).

The problem is happened because when running flutter doctor --android-licenses, it implicitly running the sdk tools which is only works with JDK 8 (afaik, correct me if I'm wrong).

因此，您需要安装 JDK 8 并将 JAVA_HOME 设置为 JDK 8 的安装路径.

So, you need to install JDK 8 and set your JAVA_HOME to your JDK 8 installation path.
