在命令行中构建项目时如何更改存储库的Maven构建路径

Question

I am building a .war file for my Maven project after checking out the project from SVN using:

mvn clean package

However, it appears that Maven search for the libraries (maven dependencies) based on the current location of the project folder. (Underlined in yellow as below image). The project was placed in D:\\DCA

I want mvn to search for the libraries from my .m2 repository folder instead of D:\\DCA\\.. . I believe there is a config file or settings file somewhere which allows me to change the location of the repository for project building.

So my question is : Where/how can I change the path as underlined in yellow in the above image?

After you have downloaded the maven, follow given simple steps to change maven local repository location to some other path.

• Navigate to path {M2_HOME}\\conf\\ where M2_HOME is maven installation folder.
• Open file settings.xml in edit mode in some text editor.
• Find the tag Update the desired path in the value of this tag.

• Save the file. http://maven.apache.org/xsd/settings-1.0.0.xsd">

    <!-- localRepository | The path to the local repository maven will use to store artifacts. | | Default: ${user.home}/.m2/repository --> <localRepository>E:/devsetup/M2</localRepository> </settings> 

==============================================

Start maven with -X option (debug) and examine the beginning of the output.

There should be something like this

[INFO] Error stacktraces are turned on.

[DEBUG] Reading global settings from c:....\\apache-maven-3.0.3\\conf\\settings.xml

[DEBUG] Reading user settings from c:.....m2\\settings.xml

[DEBUG] Using local repository at C:....\\repository

Here you can see from where Maven is picking up the setting.

====================================================

If you want to specify your own settings.xml then

mvn --settings customSetting.xml clean install

or

mvn -s customSetting.xml clean install
