Maven的编译无法识别我的本地回购依赖 [英] maven compile does not recognize my local repo dependency

问题描述

我有一个本地jar文件要导入到我的文件夹中，并且我已经运行了mvn install:

I have a local jar file to import into my folder, and I have run the mvn install:

mvn install:install-file -Dfile="C:\myapp\Development\core\target\api-core-1.0.0.jar" -DgroupId="com.myapp" -DartifactId="api-core" -Dversion="1.0.0" -Dpackaging=jar

这是成功的:

[INFO] Building api-malloc 0.0.1
[INFO] ------------------------------------------------------------------------
[INFO]
[INFO] --- maven-install-plugin:2.4:install-file (default-cli) @ api-malloc ---

[INFO] BUILD SUCCESS

从.me文件夹中，我还可以看到生成了相应的文件:

From the .me folder, I can also see that the appropriate files are generated:

在pom.xml文件中，我有:

In the pom.xml file, I have:

安装jar文件后，我还做了一个maven更新项目.

I also did a maven update project after installing the jar file.

但是Eclipse仍然抱怨无法将依赖项api-core-1.0.0.jar中的类解析为一种类型.

However Eclipse still complain about the classes from that dependency api-core-1.0.0.jar cannot be resolved to a type.

我想念什么?

在错误仍然存​​在的情况下，行中已经包含了maven的settings.xml文件.

The maven's settings.xml file is already included the lines while the error persist.

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository>C:/Users/username/.m2/repository</localRepository>
  <offline>false</offline>

在Eclipse中，maven设置是正确的:

And in Eclipse, the maven setting is correct:

推荐答案

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                          http://maven.apache.org/xsd/settings-1.0.0.xsd">
      <localRepository>${userhome}/.m2/repository</localRepository>
      <offline>false</offline>
</settings>

尝试将其添加到settings.xml 在$ {userhome}/.m2/下创建(如果不存在).

try to add this to settings.xml Create on under ${userhome}/.m2/ if it does not exists.
