Why does maven not copy the properties files during the build process?

问题


Nothing I've found has been able to help me solve this one specific case. I recently switched from a plain old java web app project (which was working) to a maven web project. I get the following runtime exception:

java.util.MissingResourceException: Can't find bundle for base name com.myapp.config, locale en

I am using Netbeans to create a JSF 2.0, Spring, and Hibernate web app. I have the following directory structure:

src\main\java\com\myapp     Contains config.properties
src\main\resources               Empty

target\myapp\WEB-INF\classes\com\myapp     Contains compiled class files without config.properties
src\main\java\com\myapp                                 Contains config.properties

Inspection of the WAR file in the target folder does not show any sign of the properties file so it's as if the Maven build plug-in is not copying over properties files. I know there is a tag you can place inside the pom but it didn't work for me. The link below mentions that the resources folder (empty for me) has its contents included during the build but if that is the case, how do you do it from Netbeans? I just want the properties file to be packaged with my war so it is accessible when it is deployed to the server.

What is your project's build path configured to be in Netbeans? You might try changing it to src/main/webapp/WEB-INF/classes. This way class files compiled from your src/main/java folder and any resources you have under src/main/resources should get included in the generated WAR. You would then be able to access your config.properties file if you place it under the src/main/resources folder.

You might also review any includes sections in your pom.xml and ensure you're not accidentally excluding something (if you explicitly include some things, you're likely implicitly excluding everything else).




回答2:


Maven doesn't copy resources from the java source tree by default, but you can get it do that by adding this to your pom.xml:

<build>
  <resources>
    <resource>
      <directory>src/main/java</directory>
      <excludes><exclude>**/*.java</exclude></excludes>
    </resource>
  </resources>
</build>

Make sure you exclude the java source files.

Try putting your config.properties under src\main\resources\com\myapp. I was able to test this on a local project. I'm running Maven 3.0.2.

Created a mvn sample project with the webapp archetype:

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp

Created a directory at src/main/resources/com/foo and put a foo.properties file under it.

Ran a build:

mvn clean install

Then, when looking in the resulting target directory, the foo.properties file appears:

ls -al target/my-webapp/WEB-INF/classes/com/foo/
-rw-r--r--  1 sblaes  staff    4 Apr  2 22:09 foo.properties

You might try those steps on your machine. If that works, then start trying to simplify your POM above by removing things from it to see if it starts working. Trial and error is no fun, but I just don't see anything above that should be breaking it.

By default maven will include all files under resources folder. If your properties files are not in the resource folder, then you need to include the following in the pom.xml file under the build section.

<build>
/* other tags like <plugins> goes here */
<sourceDirectory>src/main/java</sourceDirectory>  
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
            </includes>
        </resource>
    </resources>
/* other tags like <plugins> goes here */
</build>
