创建新的Maven项目时出错

Question

当我尝试创建一个新的Maven项目（具有多个原型，不仅是下面的一个）时，我遇到此错误：

Unable to create project from archetype [org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE]
Unable to add module to the current project as it is not of packaging type 'pom'

有谁知道为什么会这样，如何解决？

Answer 1

您的目录似乎不为空。此命令行对我有用：（在空目录中）

mvn archetype:generate -DgroupId=fr.myGroupId -DartifactId=MyApplication -Dpackagename=fr.myGroupId -DarchetypeArtifactId=maven-archetype-quickstart

结果是：

[INFO] Using property: groupId = fr.myGroupId
[INFO] Using property: artifactId = MyApplication
Define value for property 'version':  1.0-SNAPSHOT: : 
[INFO] Using property: package = fr.myGroupId
Confirm properties configuration:
groupId: fr.myGroupId
artifactId: MyApplication2
version: 1.0-SNAPSHOT
package: fr.myGroupId
 Y: :

我可以通过在新创建的目录中执行以下命令行来重现您的错误：

cd MyApplication
mvn archetype:create -DgroupId=fr.myGroupId -DartifactId=MyApplication -Dpackagename=fr.myGroupId -DarchetypeArtifactId=maven-archetype-quickstart
[...] [INFO] BUILD FAILURE
