如何使Maven版本插件更新父目標與多模塊項目一起工作

Question

我使用versions-maven-plugin的版本2.1。

我有一個源代碼樹這樣的：

+-- JavaProjects 
    +-- customs-deployment-support 
     +-- pom.xml 
    +-- pom.xml  (a.k.a. base-parentpom) 
+-- Projects 
    +-- customs-template 
     +-- pom.xml 
    +-- customs-ear-template 
     +-- pom.xml 
    +-- customs-rpm-template 
     +-- pom.xml 
    +-- customs-site-template 
     +-- pom.xml 
    +-- pom.xml  (a.k.a. customs-parentpom) 

現在上述情況，<parent />爲customs-template項目customs-deployment-support。所有其他customs-*-template項目的<parent />是base-parentpom。

注：customs-parentpom只是一個「聚合器」，而不是任何海關模塊真正的父母，但它確實申報每個customs-*項目作爲其<modules />節一<module />。

對於SNAPSHOT版本構建這個偉大的作品。

現在，我想移動到versioned工件，其中每個工件的版本簽名是類似於x.x.x_yyyyMMddhhmm_nn。

所以，現在我想聘請versions-maven-plugin打造customs-parentpom（或「聚合器」 pom.xml）

我用詹金斯構建。所以我配置的預步驟卷染各海關項目的<parent />部分中的版本，喜歡的東西：

mvn versions:update-parent 

我希望它找到最新的上游文物（即base-parentpom和customs-parentpom）中的Nexus可用。

但它失敗...

考慮，我從來沒有想詹金斯以在上述情形SNAPSHOT版本神器。我意識到SNAPSHOT在本地.m2存儲庫中不可用。我真的需要一個版本插件才能正確解析嗎？

我在做什麼錯？甚至有可能做我想做的事情？如果有幫助，我願意共享pom.xml文件。

所以這只是我的誤解而已。如果您使用多模塊設置，則需要確保在簽出源代碼時爲了構建模塊，必須能夠將其路徑追溯到parent（通過<relativePath />）。

我正在簽出一個模塊，但不是它的父類;因此我得到了non-resolvable parent POM錯誤。

因此，爲了讓反應堆盡其所能，您需要定義聚合器（和/或父代）pom.xml中的所有模塊。

然後你就可以建立一個（或多個）模塊（項目），像這樣

mvn clean install --projects <project1>,<project2> --amd
