android - 无法通知项目评估监听器 > javax/xml/bind/annotation/XmlSchema

Question

我尝试首先使用 react-native run-android 运行一个 react-native 应用程序。我希望它能正常工作，就像我调用 react-native run-ios 时一样。堆栈中有很多用户出现相同类型的错误，“无法通知项目评估监听器”。

如对 bug 的评论中所述由 OP 提交，Gradle 似乎在 Java 9 或更高版本中存在问题。

您需要安装 JDK 8(JRE 不够用，8 之后的版本将无法运行)并告诉 Gradle 使用它，而不是您系统上的默认 Java 版本。

在我的例子中(运行 Ubuntu 18.04)，这需要安装 openjdk-8-jdk(我已经有 JDK 11 和 JRE 8，但没有 JDK 8)。

您有多种方式告诉 Gradle 使用 JDK 8(在所有示例中，将路径替换为 JDK 安装的实际路径；此处显示的方式对 Ubuntu 18.04 amd64 有效):

1. 使用选项运行 Gradle

   -Dorg.gradle.java.home=/usr/lib/jvm/java-8-openjdk-amd64
   

2. 确保 ~/.gradle/gradle.properties 包含行

   org.gradle.java.home=/usr/lib/jvm/java-8-openjdk-amd64
   

3. 在您的 build.gradle 中包含以下几行:

   compileJava.options.fork = true
   compileJava.options.forkOptions.executable = /usr/lib/jvm/java-8-openjdk-amd64
   

这帮助我在不同的项目中摆脱了同样的错误。
