Added Maven dependency, Eclipse doesn't see it
提问by markvgti
I add guava 17.0 to my pom.xml, Eclipse automatically rebuilds project.
我将 guava 17.0 添加到我的 pom.xml，Eclipse 会自动重建项目。
Ran mvn dependency:resolve, maven shows com.google.guava:guava:jar:17.0:compilein the list of resolved files.
Ran mvn dependency:resolve，maven 显示com.google.guava:guava:jar:17.0:compile在已解析文件列表中。
However when in Eclipse I try to auto-complete com.google.g, it says "No default proposals". I've added dependencies in my pom.xml before, run mvn dependency:resolveand Eclipse picked them up immediately. What's different this time?
但是，当我在 Eclipse 中尝试自动完成时com.google.g，它显示“没有默认建议”。我之前在我的 pom.xml 中添加了依赖项，运行mvn dependency:resolve和 Eclipse 立即获取它们。这次有什么不同？
I've tried the following so far:
到目前为止，我已经尝试了以下方法：
- Tried cleaning the project and letting it automatically rebuild.
- Clean, auto-rebuild, re-start Eclipse.
mvn cleanfollowed bymvn install- https://stackoverflow.com/a/6913992/91933

- https://stackoverflow.com/a/2393810/91933(although I couldn't get Eclipse to accept $HOME/.m2 as the Maven repository (which it is)).
- 尝试清理项目并让它自动重建。
- 清理，自动重建，重新启动 Eclipse。
mvn clean其次是mvn install- https://stackoverflow.com/a/6913992/91933

I can see target/<projname>-1.0-SNAPSHOT/WEB-INF/lib/guava-17.0.jar.

The suggestion by @khmarbaiseworks best and solves all problems.
@khmarbaise的建议效果最好，可以解决所有问题。
Just delete the project from Eclipse.
Re-import as "Existing Maven Projects" and point it towards the directory that contains the project's
pom.xmlfile.Let Eclipse's
m2eplugin handle the rest
只需从 Eclipse 中删除该项目。
重新导入为“现有 Maven 项目”并将其指向包含项目
pom.xml文件的目录。让 Eclipse 的
m2e插件处理剩下的事情
Worked flawlessly for me.
对我来说完美无缺。
The following advice (taken from https://developers.google.com/appengine/docs/java/webtoolsplatform#maven) may only apply to GAE projects, but seems like it should be generally applicable (my project is GAE, so can't be sure):
以下建议（取自https://developers.google.com/appengine/docs/java/webtoolsplatform#maven）可能仅适用于 GAE 项目，但似乎应该普遍适用（我的项目是 GAE，所以可以'不能肯定）：
The directory at the root of the Maven project must notcontain any of the following:
1. A subdirectory named target 2. A subdirectory named .settings 3. A file named .classpath 4. A file named .project
Maven 项目根目录下不得包含以下任何内容：
1. A subdirectory named target 2. A subdirectory named .settings 3. A file named .classpath 4. A file named .project

In file pom.xmlinside < dependency > seleneiummaybe you have defined < scope> teste.g. < scope>test < /scope>.
在pom.xml里面的文件中< dependency > seleneium，您可能已经定义了< scope> test例如< scope>test < /scope>.
Removing/deleting this also can solve your problem.
删除/删除它也可以解决您的问题。
