The reason: ojdbc should be charged so maven can not be downloaded through a central warehouse.
I thought it was a bad network, leading to the download has failed, but how I think are wrong, because I used the image of Ali cloud, the network can be no question of it, so they use outside the network, re-import, or failure.
I went to the central warehouse to find maven nor, later found on the Internet turned out to be ojdbc for a fee
So the solution is as follows:
1. Download the men ojdbc14.jar, the same as the following
Here you have to Tucao CSDN, and also money to download, I like this white whore party how could a penny
2. After downloading ojdbc14, renamed ojdbc14-10.2.0.4.0.jar, as follows
3. Open and then enter cmd
mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc14 -Dversion=10.2.0.4.0 -Dpackaging=jar -Dfile=E:\oracle\ojdbc14-10.2.0.4.0.jar
After the Enter key, if there is no problem, it should appear as shown in Figure
And then to your local Maven repository is to see if there is a successful install.
