mvn 编译错误

Question

我已将一个 maven 项目导入到 intellij IDEA。依赖关系已成功解决。但是在运行时

    sudo mvn install

从终端它给出了这个错误。

  [ERROR] BUILD FAILURE
  [INFO] ------------------------------------------------------------------------
  [INFO] Compilation failure

之前我也将这个项目导入到 eclipse 中。然后从 eclipse 运行 mvn install 它给出了不同类型的错误。

在那之后运行

 sudo mvn install 

从终端可以构建成功。 我不明白这种行为的原因。如果有办法解决问题第一部分中出现的错误，那真的会有所帮助。

Answer 1

请参阅Maven Compiler Plugin Documentation。设置正确的源和目标电平。那应该可以解决它。

Answer 2

只需像这样定义编译器目标/源：

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
          <source>1.5</source>
          <target>1.5</target>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>

注解至少需要1.5。

Answer 3

在 pom.xml 中搜索“源”。
一定有错误的值。
源是指编译代码的 Java 版本。
如果Java代码中有注解，需要设置version >= 1.5

Answer 4

听起来你的编译器插件配置不完整

你的 Jdk 等级应该大于 1.5

示例 pom.xml 配置

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
            <source>1.7</source>
            <target>1.7</target>
        </configuration>
    </plugin>
