无法从“17”确定 java 版本

Question

当我将 Spring 工具套件 4.12.1 中的 Spring Boot 项目设置为 Gradle(STS) 项目时，我收到类似“无法从 '17' 确定 java 版本。但项目使用的是 java 11。Gradle 版本是6.8.3. 我从git成功克隆项目。我的机器已经安装了Java 11。但是不能作为Gradle(STS)导入。谁能帮帮我。我是spring工具套件的新手。

您可以在下面看到我的异常堆栈跟踪。

Answer 1

这很可能是由于项目正在使用的 Gradle 版本尚不支持用于运行 IDE 的 JDK。在您的情况下，IDE 似乎在嵌入式 JDK17 上运行，Gradle 可能尚不支持（不确定，但异常看起来像那样）。

您可以通过两种不同的方式解决此问题：

一种解决方案是更新项目中使用的 Gradle 版本。 Gradle 7.3 支持 JKD17 并将您的项目切换到该版本应该允许 IDE 很好地导入它（通常在 gradle-wrapper.properties 文件中）。

另一种解决方案是修改SpringToolSuite4.ini 文件中的-vm 设置，并让它指向来自旧版JDK 的Java 可执行文件（至少是JDK11，但也许您的项目Gradle 版本也适用于JDK16） .更改后，再次打开 IDE 并尝试再次导入您的项目。
