java - Maven 不断搞乱我的 Java 编译器和构建路径设置

Question

发生了什么:我的 java 编译器设置从自定义 jdk 重置为默认 java se1.5
当它发生时:每次我单击 maven- 更新项目(当然在 eclipse 中)。

我认为这与更新项目设置复选框有关。但是我在我的 pom 中找不到负责配置我的 eclipse 项目的标签。有什么提示吗？

顺便说一句，我不能只取消选中该框，因为 pom 可能有其他对我的项目至关重要的设置

编辑:抱歉耽搁了，这是我的 pom.xml

Answer 1

我不太确定你的问题，但我相信 m2e 插件通过编译器插件的设置获得源/输出版本。

在你的POM中，有类似

的东西

....
<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
        <source>1.6</source>
        <target>1.6</target>
      </configuration>
    </plugin>
      .....
  </plugins>
</build>

m2e应该能够根据源和目标版本配置你的Eclipse
