9.我有一个jar,我想把它放在我自己本地仓库.我怎样把它拷贝进去?
If you understand the layout of the maven repository, you can copy the jar directly into where it is meant to go. Maven will find this file next time it is run.
If you are not confident about the layout of the maven repository, then you can adapt the following command to load in your jar file, all on one line.
mvn install:install-file
-Dfile=
-DgroupId=
-DartifactId=
-Dversion=
-Dpackaging=
-DgeneratePom=true
Where: the path to the file to load
the group that the file should be registered under
the artifact name for the file
the version of the file
the packaging of the file e.g. jar
mvn install:install-file -Dfile= -DgroupId= -DartifactId= -Dversion= -Dpackaging= -DgeneratePom=true Where: the path to the file to load the group that the file should be registered under the artifact name for the file the version of the file the packaging of the file e.g. jar This should load in the file into the maven repository, renaming it as needed.
10.我如何取消Maven邮件列表的订约?
To unsubscribe from a Maven mailing list you simply send a message to
[mailing-list]-unsubscribe@maven.apache.org
So, if you have subscribed to then you would send a message to in order to get off the list. People tend to have problems when they subscribe with one address and attempt to unsubscribe with another. So make sure that you are using the same address when unsubscribing that you used to subscribe before asking for help.
If you find you still cannot get off a list then send a message to [mailing-list]-help@maven.apache.org. These instructions are also appended to every message sent out on a maven mailing list ...

13.在我的依赖中如何包含tools.jar?
The following code includes tools.jar on Sun JDKs (it is already included in the runtime for Mac OS X and some free JDKs).
Tests are run by the surefire plugin. The surefire plugin can be configured to run certain test classes and you may have unintentionally done so by specifying a value to ${test}. Check your settings.xml and pom.xml for a property named "test" which would like this:
...
test
some-value
...
or
...
some-value
...
... testsome-value ... or ... some-value ...
