Maven2: Missing artifact but jars are in place

Question

From now to then, my Maven 2 started to mess around.

I am using SPring STS 2.6.1 and have a single project based on Spring 3, Hibernate, DWR, Cometd and all that stuff.

Today I just updated from Git und all of a sudden, I got that scary mvn exclamation mark (!) next to my project.

After hitting "Project -> Maven -> Update dependencies" I just receive:

I then checked on my Mac /Users/XYZ/.m2 and all jar files are in place as expected.

I am using the current Maven release shipped with STS. I also enabled debug output but there was nothing suspicious.

Answer 1

After not much success with any of the answers available here so far.

My solution:

I downloaded the jar file manually and then installed the dependency by using Apache Maven install:install-file plugin, see more details here

A Full Example:

<dependency>
     <groupId>commons-net</groupId>
     <artifactId>commons-net</artifactId>
     <version>3.4</version>
</dependency>

1. Download jar file from here

2. Install it by using the following command:

mvn -X install:install-file " -DgroupId=commons-net" "-DartifactId=commons-net" "-Dversion=3.4" "-Dpackaging=jar" "-Dfile={your_full_downloads_path}/commons-net-3.4.jar"

3. Click on the project and select Maven->Update Project

Answer 2

I had the same problem, maven was complaining about a missing artifact, even though it existed in .m2/repository/[...]. In my case the problem was that I forgot to specify the correct repository in the pom.xml from which the package was downloaded originally (download by another project).

Adding the package repository to the pom.xml solved the problem.

<repositories>
  <repository>
    <id>SomeName</id>
    <name>SomeName</name>
    <url>http://url.to.repo</url>
  </repository>
</repositories>

Thanks Maximilianus for the hint to those "*.repositories" files in the package directory.

Answer 3

i download the missing jar and placed in the .m2 repository fixed the problem =]

Answer 4

I was facing the same issue and below step removed all these errors :

• Right click Project -> Maven -> Update Project

Answer 5

The following steps worked for me.

1) Cut all the contents from pom.xml file and keep it another file and save the pom.xml
2) Just delete .m2 folder(entire maven repository) and restart the eclipse(or jbdevstudio)
3) paste the previous pom.xml file content(from the cut file) and all the error are gone.

Answer 6

If the other solutions didn't work and you know the correct jars are in your repository then:

The problem is that eclipse caches the errors for some reason.

I solved this problem by deleting the errors in the Problems tab and then I refreshed the project explorer and all the exclamation points and errors never returned.
