如何在Intellij IDEA 12中设置maven项目

Question

我在将由Netbeans创建的maven项目导入IDEA 12时遇到问题.在pom中写入的依赖项工件不起作用.它告诉我"无法在"import org.springframework.xxx;"上解析符号'springframework'".当我运行它时,它表示org.springframework.xxx不存在.这是pom文件

Answer 1

如果项目在命令行(mvn clean install)上运行,那么它在100%的可能性也会在IntelliJ 12中运行:-)

在文件 - >项目导入 - >从外部Maven模型后,您应该看到模块.

我在IntelliJ设置中检查的是maven主目录的位置(文件 - >设置 - > Maven)以及它读取(或不读取)的settings.xml文件.

在mvn installIDE中不应该在命令行上会发生什么不同.如果是这样,它会比较mvn help:effective-settings命令行和IntelliJ的输出(也许来自Netbeans).

如果您没有看到所有模块,请右键单击parent-pom.xml并选择maven - > reimport.要解决依赖关系,您必须执行一次安装.它并不会在所有情况下自动解决依赖关系.

Answer 2

当pom.xml文件在项目中可用时,您可以通过运行以下命令生成IntelliJ构思项目所需的文件:

mvn idea:idea
