Question

我正在尝试执行此操作：

mvn archetype:generate -DgroupId=org.sonatype.mavenbook.simple -DartifactId=simple - DpackageName=org.sonatype.mavenbook -Dversion=1.0-SNAPSHOT"

但是它显示了这个错误：

C:\TPMaven>mvn archetype:generate -DgroupId=org.sonatype.mavenbook.simple -DartifactId=simple - DpackageName=org.sonatype.mavenbook -Dversion=1.0-SNAPSHOT

[ERROR] Re-run Maven using the -X switch to enable full debug logging.

我的maven声明有什么问题？

Answer 1

正确的代码应该是：

mvn archetype:generate -DgroupId=org.sonatype.mavenbook.simple -DartifactId=simple -DpackageName=org.sonatype.mavenbook -Dversion=1.0-SNAPSHOT

如果您使用Win，则运行cmd.exe中的上述代码即可。

如果您在PowerShell中运行代码，请使用以下代码：

mvn archetype:generate "-DgroupId=org.sonatype.mavenbook.simple" "-DartifactId=simple" "-DpackageName=org.sonatype.mavenbook" "-Dversion=1.0-SNAPSHOT"

您的代码中有两个错误：

mvn archetype：generate -DgroupId = org.sonatype.mavenbook.simple -DartifactId = simple - DpackageName = org.sonatype.mavenbook -Dversion = 1.0-SNAPSHOT＆＃34;

- DpackageName

应该是

-DpackageName

-Dversion = 1.0-SNAPSHOT＆＃34;

应该是

-Dversion=1.0-SNAPSHOT

您的一个命令行参数之间有一个空格。运行命令：

    acanby@PANAMERA /c/projects/mvntest $ mvn archetype:generate -DgroupId=org.sonatype.mavenbook.simple -DartifactId=simple - DpackageName=org.sonatype.mavenbook -Dversion=1.0-SNAPSHOT

将- DpackageName=...部分修复为-DpackageName=...：

acanby@host /c/projects/mvntest$ mvn archetype:generate -DgroupId=org.sonatype.mavenbook.simple -DartifactId=simple -DpackageName=org.sonatype.mavenbook -Dversion=1.0-SNAPSHOT
