沒有發現甲醛在創建從原型

Question

新項目，我試圖執行此：

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

，但它顯示了這個錯誤：

C:\TPMaven>mvn archetype:generate -DgroupId=org.sonatype.mavenbook.simple -DartifactId=simple - DpackageName=org.sonatype.mavenbook -Dversion=1.0-SNAPSHOT 
[INFO] Scanning for projects...

[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. 
[ERROR] Re-run Maven using the -X switch to enable full debug logging. 
[ERROR] 

這有什麼錯我的Maven的聲明？

您的一個命令行參數之間有空格。運行你的命令：

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

殺青- DpackageName=...部分-DpackageName=...：

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

正確的代碼應該是：

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

如果你用Win，運行上面的代碼在cmd中。 exe是好的。

如果您在PowerShell中運行的代碼，請使用下面的代碼：

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

---

有兩個錯誤在你的代碼：

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

1. - DpackageName

應該是

-DpackageName 

-Dversion=1.0-SNAPSHOT"

應該是

-Dversion=1.0-SNAPSHOT
