gradle openjdk 14 不受支持 class 文件主要版本 58

Question

我正在尝试运行使用 openjdk 14 构建 gradle 6.3，目标是 java 14。我收到以下错误。我知道这与编译文件的版本有关，但我的理解是 gradle 6.3 支持 java 14.

$ ./gradlew build
> Task :shadowJar FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':shadowJar'.
> Unsupported class file major version 58

$ ./gradlew -v

Answer 1

在您发布 build.gradle 后，我注意到您有以下插件：

id "com.github.johnrengelman.shadow" version "5.0.0"

我查了 Gradle plugin page，发现最新版本是 5.2.0。

更新到最新版本应该可以解决您的问题。
