正如对OP 提交的错误的评论中所述，Gradle 似乎在 Java 9 或更高版本上存在问题。

您需要安装 JDK 8（JRE 是不够的，8 以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。

在我的情况下（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）。

您可以通过多种方式告诉 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；此处显示的方法适用于 Ubuntu 18.04 amd64）：

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包含该行

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

3. 在您build.gradle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。
