【问题描述】：
我有项目（Web 服务）要在 Java 中维护。构建该项目的开发人员告诉我，他们使用了 Java 11 和 Gradle。所以我已经安装了：
- OpenJDK 服务器 VM Corretto-11.0.11.9.1（内部版本 11.0.11+9-LTS，混合模式，模拟客户端）
- Gradle 7.0.2
- Eclipse IDE 2021-06 (4.20.0)
在 Windows 10 上。 在Eclipse中配置代理服务器并下载所有更新结果和更新前一样，10785错误，其中一些是：
ActiveProfiles cannot be resolved to a type
ActiveProfilesResolver cannot be resolved to a type
After cannot be resolved to a type
ApplicationPidFileWriter cannot be resolved to a type
Autowired cannot be resolved to a type
然后我安装了 Spring Tool Suite 4 4.11.0.RELEASE 并得到了相同的错误集。 IntelliJ IDEA 2021.1.2 (Community Edition) Build #IC-211.7442.40 让我更加幸运。 我设法构建项目和 jar 文件，然后我在测试服务器上复制了 jar 文件（CentOS Linux 版本 7.5.1804 与 OpenJDK 64 位服务器 VM AdoptOpenJDK build 11.0.7+10，混合模式) 运行 jar 文件，结果出错：

我什至尝试过使用 Apache NetBeans IDE 12.0 在 NetBeans 中构建项目的结果是：
> Task :compileJava NO-SOURCE
> Task :processResources NO-SOURCE
> Task :classes UP-TO-DATE
> Task :jar UP-TO-DATE
> Task :assemble UP-TO-DATE
> Task :build
> Task :common:rina-commons:compileJava FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':common:rina-commons:compileJava'.
> Could not target platform: 'Java SE 11' using tool chain: 'JDK 8 (1.8)'.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Get more help at https://help.gradle.org

【问题讨论】：
-
您使用的是不支持 java11 的 Spring Boot 版本。所以要么升级库（Spring Boot 和朋友），要么降级 JDK。
