Subject [jira] Closed: (MNG-4907) Wrong error message when relativePath wrong
Date Sun, 21 Nov 2010 15:24:03 GMT

     [ http://jira.codehaus.org/browse/MNG-4907?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benjamin Bentmann closed MNG-4907.
----------------------------------

       Resolution: Fixed
    Fix Version/s: 3.0.1
         Assignee: Benjamin Bentmann

The referenced parent POM lacks the version and as such can't match the requirement of the
child POM. Improved error message in [r1037475|http://svn.apache.org/viewvc?view=revision&revision=1037475].

> I'll attach a zipped sample showing the issue; it has 3 folders, each having a small
pom.  They are named childFolder, parentFolder, and submodule.
> The child has the parent as its parent.
> The child has a <modules> section listing the parent and the submodule as things
to be built.
> The submodule list "parent" as its parent, but fails (on purpose, to illustrate the issue)
to include a <relativePath> element.
> If I do mvn clean on the "submodule", it says, correctly:
> [ERROR] The build could not read 1 project -> [Help 1]
> [ERROR]
> [ERROR]   The project t:submodule:1-SNAPSHOT (D:\mavenAlign\trunk\mvn-parent-relative-path\submodule\pom.xml)
has 1 error
> [ERROR]     Non-resolvable parent POM: Could not find artifact t:parent:pom:1-SNAPSHOT
and 'parent.relativePath' points at wrong local POM @ line 8, column 11 -> [Help 2]
>    Note: line 8, column 11 is right after the "<parent>" element in the source.
> But, if I run mvn clean on the "child", it says, incorrectly:
> [ERROR] The build could not read 1 project -> [Help 1]
> [ERROR]
> [ERROR]   The project t:child:1-SNAPSHOT (D:\mavenAlign\trunk\mvn-parent-relative-path\childFolder\pom.xml)
has 1 error
> [ERROR]     Non-resolvable parent POM: Could not find artifact t:parent:pom:1-SNAPSHOT
and 'parent.relativePath' points at wrong local POM @ line 5, column 11 -> [Help 2]
> In fact, the ...\childFolder\pom.xml doesn't have an error, and the message that it points
at the wrong local POM at line 5, column 11 is not correct.  If you comment out the <module>
reference in this pom to the "submodule", it works fine.  The error is actually in the submodule.
 The line 5, column 11 refers to a spot right after the "<parent>" element in the child
module, where everything is OK.
> This of course, misleads the person trying to debug this, to look hard in the wrong place
:-).
