eclipse/maven/sonatype war build可以在命令行運行，但不能在eclipse中運行

我的（簡單）war項目在命令行中使用mvn：package生成良好，但無法使用maven通過sonatype插件在eclipse中生成。我得到的錯誤是：eclipse/maven/sonatype war build可以在命令行運行，但不能在eclipse中運行

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1-alpha-1:war (default-war) on project shoploops_webapp: Execution default-war of goal org.apache.maven.plugins:maven-war-plugin:2.1-alpha-1:war failed: dependenciesInfo : dependenciesInfo

path    : /webapp-structure/dependenciesInfo

我真的有兩個問題 1）如何解決這個問題？ 2）爲什麼mvn：package在命令行上工作正常，但不通過插件？他們在工作方式上有什麼區別，這樣會出現這樣的錯誤？

非常感謝！

編輯：在調試模式下運行它的堆棧跟蹤：

謝謝帕斯卡！你已經救了我的理智了！我更新eclipse以使用與我從命令行構建相同版本的maven，現在它完美地構建:-) – Jeremy 2010-05-12 17:27:22

爲什麼mvn:package做工精細在命令行，而不是通過插件？他們在工作方式上有什麼區別，這樣會出現這樣的錯誤？

短的版本是，m2eclipse的不不使用，除非你告訴他這樣做（這將是我的建議），您在命令行中使用相同的版本。如果你想知道，m2eclipse使用嵌入式Maven 3（Maven Embedder 3.0.0.200912160759）。

我該如何解決這個錯誤？

實際上，問題記錄在http://jira.codehaus.org/browse/MWAR-187，它提供了幾種解決方法。

降級Maven的戰爭插件2.1-α-1

通過修改Maven的戰爭插件配置

<configuration> 
    <useCache>false</useCache> 
</configuration>

禁用緩存。我想，在配置M2Eclipse不使用Maven Embedder（但在CLI上使用的版本）也可以解決問題，這是我的建議。您會在窗口>首選項> Maven中找到該設置。

你需要去preferences->maven->installation並選擇你的外部安裝。我正在使用springsource工具套件。但是maven配置路徑應該和其他eclipse類型相同。

我得到了同樣的問題，但做了mvn install。在命令行中工作良好，但在Eclipse中失敗。

實際發生的是顯然我的webapp-cache.xml文件已損壞。我解決了運行mvn clean install的問題。
