java - Maven not downloading dependencies in Eclipse -

-

i setting project in eclipse . projects builds through command line(all mvn commands mvn package, mvn compile, mvn clean install) work fine. while setting project on sts or eclipse . see of dependencies not getting downloaded though present in pom.xml. however, searching them in maven repository , downloading jar local computer , adding them build path makes work on eclipse.

is there need eclipse make sure downloads dependencies repository.

my pom:

<dependency>     <groupid>org.apache.bookkeeper</groupid>     <artifactid>bookkeeper-server-compat410</artifactid>     <version>4.1.0</version>     <scope>test</scope>     <exclusions>         <exclusion>             <groupid>org.apache.bookkeeper</groupid>             <artifactid>bookkeeper-server</artifactid>         </exclusion>     </exclusions> </dependency> <dependency>     <groupid>org.apache.bookkeeper</groupid>     <artifactid>bookkeeper-server-compat420</artifactid>     <version>4.2.0</version>     <scope>test</scope>     <exclusions>         <exclusion>             <groupid>org.apache.bookkeeper</groupid>             <artifactid>bookkeeper-server</artifactid>         </exclusion>     </exclusions> </dependency>

both these artifacts not downloaded eclipse , there jars found http://mvnrepository.com/artifact/org.apache.bookkeeper/bookkeeper-server-compat410/4.1.0 , http://mvnrepository.com/artifact/org.apache.bookkeeper/bookkeeper-server-compat420/4.2.0 not present in folder mavendependencies , subsequently giving errors in eclipse.

however manually adding them build path created new folder (reference library) , resolved eclipse errors . why did eclipse not download , import these dependencies maven repository ?? bug in eclipse or problem side . please help.

solution 1:

set correct proxy:

<proxy>     <id>optional</id>     <active>false</active>     <protocol>http</protocol>     <username></username>     <password></password>     <host>172.27.171.91</host>     <port>8080</port> </proxy>

solution2 :

just delete 

lastupdated extension files folder

and try updating maven.

[most of times solution work]
