Eclipse: The archive which is referenced by the classpath, does not exist

Question

My Eclipse is Indigo Java classic.

I have a java project which has mockito-all as a dependency. pom.xml:

    org.mo         


        

Answer 1

Go to Window > Show View > Navigator

There you will see .classpath file where the dependencies related to your M2 Repo can be seen

An example would be -

<classpathentry 
 exported="true" 
 kind="var" 
 path="M2_REPO/javax/activation/activation/1.1.1-redhat-2/activation-1.1.1-redhat-2.jar"/>

Change the version to the one under

Project Explorer > Your Project > Libraraies > Maven Dependencies

Hopefully this will resolve the issue.

Answer 2

I had a similar problem while I was trying to start my tomcat. I would suggest that you check "Classpath" the following way:

1) Run Configurations

• Right click on your project
  • then click "Run" -> "Run Configurations..."
  • there check your settings for you project (e. g. in my case it was the Apache Tomcat)
  • here look into you tab "Classpath" under "User Entries"

2) Project classpath

• Right click on your project -> "Properties" -> "Java Build Path"
  • now check the "Source" Tab as well as your "Libraries" Tab
  • Problems should be marked red in the "Libraries" tab

Answer 3

In my case I had a JRE installed then added a JDK. ANT seemed to stick with the JRE even though I changed my project to use the JDK.

To fix this I had to do: 1. Select "Run As..." 2. Select the second "Ant build..." option 3. This brings up a panel to allow setting configuration. Choose the "JRE" tab and change the selected JRE to the JDK

Answer 4

It might be the version issue of java and eclipse.

I upgraded from kepler to mars and I was using JAVA 1.7. I faced the same issue with tools.jar.

I downgrade the eclipse and this time build ran successfully. It might help you.

Answer 5

If any of the previous answers didn't work, try this : Right click on your project -> Debug As -> Open Debug Dialog ... -> In the classpath you'll find the jar causing you the trouble. Remove it.

Hope this work for you as it worked for me.

Answer 6

In my case with using ANT I change the setting in Windows --> Preferences --> Ant --> Runtime --> Global Entries. You need to add tools.jar as an External Jar.
