我使用Maven的用eclipse，Compileling项目的时候把它给下面的错误

[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

可能的Maven编译器插件配置问题

您可以检查堆栈过流回答： -

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

您可以使用JDK版本正确版本

<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>
