java.lang.ClassCastException：ConditionalOnJava $ JavaVersion无法转换为org.springframework.boot.system.JavaVersion

问题描述 投票：4回答：4

我的项目在另一台PC上正常运行。但是我使用import existing maven项目在另一台PC上导入了它。

在新的PC设置中，我有以下设置：

Project -> properties -> java compiler version -> set to 1.8

Project -> project facets -> java version ->  set to 1.8

它显示JRE System Library [javaSE-1.8]

pom.xml有<java-version>1.8</java-version>和maven插件：

<plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
          <version>3.6.1</version>
          <configuration>
            <source>1.8</source>
            <target>1.8</target>
          </configuration>
        </plugin>
    </plugins>

如果我运行clean install以上设置，则以下是控制台错误：

然后我试着在一些SO答案中建议使用spring-boot-maven-plugin：

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

与此我删除/评论maven-compiler-plugin

即使我有以下情况，这也会自动更改JRE System Library [javaSE-1.6]（1.8到1.6）：

Project -> properties -> java compiler version -> set to 1.8
Project -> project facets -> java version ->  set to 1.8 
pom.xml has <java-version>1.8</java-version>

并在“问题”窗口中给出以下错误：Java compiler level does not match the version of the installed。

所以我尝试在所有地方更改版本1.6解决了版本不匹配问题，但当我运行clean install然后再次在控制台中给出相同的（上面）堆栈跟踪。

编辑：mvn dependency:tree的输出：

springboot升级后我遇到了同样的错误。 spring-boot-actuator-autoconfigure包含类conditionalOnJava，用于反向兼容java。不知何故，这个版本类在升级后在我的情况下失败了。在我的情况下，它在clean build / clean install后没有刷新，所以我删除了gradle / maven缓存。

gradle用户：

  • 删除〜/ .gradle的内容
  • gradle clean build

对于eclipse用户来说：

  • 在eclipse中刷新gradle项目（如果你使用buildship插件）
  • 通过删除遗留依赖项来清理java构建路径（项目 - >属性 - > java构建路径 - >库）

maven用户：

  • 删除〜/ .m2的内容
  • 干净安装

您的问题是由版本引起的：spring-boot-autoconfigure-2.0.1.RELEASE.jar：2.0.1.RELEASE.Maybe您的本地存储库是版本2.0.1，但您的项目正在使用其他版本。如果是我说obove，您可以删除本地存储库的2.0.1版本并尝试再次运行该项目。

如果上述情况不起作用，请检查您是否有任何依赖项的重复引用。在我的例子中，project-A依赖于project-B并在pom文件中指定。最重要的是，在buildpath-> projects上有另一个对project-B的显式引用。

删除构建路径引用解决了ConditionalOnJava $ JavaVersion无法转换为org.springframework.boot.system.JavaVersion的问题
