How can I ask Maven for a list of the default repositories?

What command can I use to ask Maven for a list of the default repositories that it searches for its dependencies? If no such command exists, where开发者_如何学JAVA else may I look to find this default list?

---

on the command line, execute

mvn help:evaluate

then, when prompted, enter

${project.repositories}

see http://maven.apache.org/plugins/maven-help-plugin/evaluate-mojo.html

---

You can output the effective pom with the command

mvn help:effective-pom

There the default repositories are listed.

---

Use the Maven Dependency Plugin to show repositories for a specific build:

mvn dependency:list-repositories

or the full path, if you still use a very old version (<2.2)

mvn org.apache.maven.plugins:maven-dependency-plugin:2.6:list-repositories

---

As a side-effect of displaying newer versions, the versions:display-dependency-updates goal of the Versions Maven Plugin also displays the names of the repositories that it searches. To display the newer versions and the repository names, run

mvn versions:display-dependency-updates
