I have a parent project with different and now I get the following error:
Failure to transfer org.jacoco:jacoco-maven-plugin:pom:0.6.2.201302030002 from http://repo.maven.apache.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. Original error: Could not transfer artifact org.jacoco:jacoco-maven-plugin:pom:0.6.2.201302030002 from/to central (http:// repo.maven.apache.org/maven2): null to http://repo.maven.apache.org/maven2/org/jacoco/jacoco-maven-plugin/ 0.6.2.201302030002/jacoco-maven-plugin-0.6.2.201302030002.pom
I tried it with 0.5.7.201204190339 AND 0.6.2.201302030002 and ${jacoco.version} . But now success :-(

If you are behind corporate firewall or other proxy then you need to create settings.xml
file and specify credentials for proxy server like below.
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<proxies>
<proxy>
<id>my_proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>{proxy server address}</host>
<port>{proxy server port}</port>
<username>{user name to be used for proxy}</username>
<password>{password to be used for proxy}</password>
<nonProxyHosts>*.google.com|localhost|127.0.0.1</nonProxyHosts>
</proxy>
</proxies>
</settings>
Other thing you may try is to delete repository directory and try again.
If you are using eclipse then you need to configure proxy settings in Eclipse too. Goto Window -> Preference -> type 'proxy' in search box.
In Network connections
, choose 'Active Provider' as Manual
and then set proxy settings for HTTP and HTTPS. Do not set proxy for SOCKS.
One of these solutions always work for me :)
