java - Maven编译java报错diamond Operator is notsupported

Question

这个问题已经有答案了:

Maven Compilation Error: (use -source 7 or higher to enable diamond operator) (4 个回答)

已关闭 6 年前。

我正在使用 Maven 和 Eclipse ，编译项目时出现以下错误

 [INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] /D:/copay/CopayMobilePassBook/src/main/java/com/cherry/copay/mpassbook/process/impl/AccountsProcessImpl.java:[17,55] diamond operator is not supported in -source 1.5
  (use -source 7 or higher to enable diamond operator)
[ERROR] /D:/copay/CopayMobilePassBook/src/main/java/com/cherry/copay/mpassbook/process/support/ReversalProcessSupport.java:[89,88] diamond operator is not supported in -source 1.5
  (use -source 7 or higher to enable diamond operator)
[INFO] 2 errors 

但是安装的JDK版本是8项目 -> 右键单击​​ -> 属性 -> 项目事实 -> java 版本是 1.8

我的maven配置有什么问题

Answer 1

可能是maven编译器插件配置问题

您可以检查堆栈溢出答案:-

maven-compilation-error-use-source-7-or-higher-to-enable-diamond-operator

您可以使用合适版本的JDK版本

<properties>
    <maven-compiler-plugin>3.0</maven-compiler-plugin>
    <jdk-version>1.8</jdk-version>

</properties>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven-compiler-plugin}</version>
        <configuration>
            <compilerVersion>${jdk-version}</compilerVersion>
            <source>${jdk-version}</source>
            <target>${jdk-version}</target>
        </configuration>
</plugin>
