java - 使用 Maven 构建 Spring Boot 应用程序遇到 Java 版本问题
问题描述
我正在尝试使用 maven build 构建应用程序。即使我已将 pom.xml 文件放置到位,它仍会返回此构建失败。我已经配置了我的 pom 没有任何问题。但我可以看到有一些与模式相关的错误返回。但没有太多关于此的信息

解决方案
根据您的日志:
Fatal error compiling: invalid target release: 1.8.0_73
您可能正在使用较低的 JDK 版本(例如 1.7)将您的项目编译为更高的目标版本(在您的情况下为 1.8.0_73)。
尝试安装 JDK 1.8 并使您的JAVA_HOME
环境变量指向它。
通常,您应该确保源 JDK 和目标 JDK 在您的pom.xml
文件和JAVA_HOME
环境变量之间匹配。
