如何解决在eclipse中通过maven导入的java项目中的依赖项？

Question

I have imported multiple projects in eclipse through maven. After importing the projects in eclipse I saw that there are some error on the project folder in project explorer. All that errors are on pom.xml.

When I opened pom.xml the error is like this:

Project build error: Non-resolvable parent POM: Failure to find org.openhie.openempi:openempi:pom:2.2.5 in http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced and 'parent.relativePath' points at wrong local POM

How to resolve this errors in eclipse? I tried a lot by adding the missing JAR's as specified in error message sometime, but still the errors are highlighting on pom.xml.

Please advice me for this.

Thanks

Answer 1

Install http://www.eclipse.org/m2e/ via the eclipse marketplace. The plugin adds a

classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"

entry in the .classpath file for eclipse and every jar from the maven dependencies will be in your classpath.

You have a maven plugin that does that. You have to go with the command line at the root of your maven project and type

mvn eclipse:eclipse

It will create (or update) an eclipse project with dependencies to the jar located in your local maven repository, and the eclipse project artifacts (.project, .classpath and other stuff) in the same repository.

Then import your project in eclipse using "Import existing project" wizard.
