Resource file is never overwritten
----------------------------------
Key: MRESOURCES-120
URL: http://jira.codehaus.org/browse/MRESOURCES-120
Project: Maven 2.x Resources Plugin
Issue Type: Bug
Affects Versions: 2.3
Environment: Windows XP Professional SP3
Maven 2.2.1
jdk1.6.0_18
Reporter: Mark Dolgov
Priority: Minor
I have the 2 resource files with the same name (config.properties) under
following locations:
Location 1: .../src/main/resources/config.properties (modification date
2009-11-25)
Location 2: .../src/main/resources/envSpecific/test/config.properties
(modification date 2009-12-21)
During build, config.properties should be put under target/classes folder.
My pom configuration (see excerpt below) makes it so that:
1. 'config.properties' file from location 1 is copied to target/classes;
2. 'config.properties' file from location 2 is copied to target/classes and
overwrites the one from previous step.
Maven really tries to do that, see maven output excerpt below.
The PROBLEM: the file, copied in step 2, does NOT overwrite the one, copied in
step 1.
Though, it works, when I set plugin property 'overwrite' == true. But since
files modification dates are different (see above), it should work with
overwrite==false.
Possible cause:
I debugged the related code a bit, and found, that maven-resources-plugin uses
plexus-utils-1.5.6.jar, and its FileUtils.class for copying.
In FileUtils, starting line 2049 there is a following code block:
------------
if ( to.lastModified() < from.lastModified() || overwrite )
{
copyFile( from, to );
}
------------
According debug,
- variable 'to' references the file, which has been already copied to
target/class folder (on step 1).
- variable 'from' references the file from the source (location 2).
In my environment to.lastModified()< from.lastModified() == false, because file
referenced by 'to' has modification date, when it was copied to class folder.
Possible solution:
I guess, 'from' file should be compared not to the one in target/class folder,
but to corresponding file from source (location 1), which was copied to class
folder (step 1).
----------------------------------------
Maven build configuration, related to resources:
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<excludes>
<exclude>envSpecific/**/*</exclude>
</excludes>
</resource>
<resource>
<directory>${basedir}/src/main/resources/envSpecific/${env}</directory>
<filtering>true</filtering>
<includes>
<include>**/*</include>
</includes>
</resource>
</resources>
Maven output (sorry, can't paste debug mode due security reasons, but it does
not report any problems with copying):
>mvn -Denv=test process-resources
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------

[INFO] Copying 6 resources
[INFO] Copying 1 resource

[INFO] ------------------------------------------------------------------------
-----------------------------------
Another minor problem, is that even though (in debug mode) maven declares
'[INFO] Copying 1 resource', but it never says, if succeeded or not.
Sorry, if not a bug or duplicate.
