Debugging tests of a Maven project in NetBeans

Lucio Benfante — Wed, 20 Feb 2008 11:30:00 -0600

Occasionally I experienced some problems in debugging test classes using NetBeans with Maven projects. Simply, the debugger started but didn’t attach to the running tests.

Eventually I discovered the reason!

I used to configure the surefire plugin with:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <skip>false</skip>
        <useFile>true</useFile>
        <forkMode>once</forkMode> <!-- always, once or never -->
        <!-- <reportFormat>plain</reportFormat> -->
        <argLine>-Xmx512M</argLine>
    </configuration>
</plugin>

The problem is the argLine parameter. It will override the parameters the Mevenide plugin will pass for debugging tests. So, I commented it in my configuration:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <skip>false</skip>
        <useFile>true</useFile>
        <forkMode>once</forkMode> <!-- always, once or never -->
        <!-- <reportFormat>plain</reportFormat> -->
        <!--argLine>-Xmx512M</argLine--> <!-- don't use if you want to debug tests in NetBeans -->
    </configuration>
</plugin>

...and now I can debug my tests!

Maven 2: Spring and JTA dependencies

Lucio Benfante — Sat, 26 Nov 2005 09:06:00 -0600

Few weeks ago I started using Maven 2 for one of my development projects. The project is very simple, but it has dependencies with some external libraries, in particular with Spring:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring</artifactId>
  <version>1.2.6</version>
  <scope>runtime</scope>
</dependency>

Introducing this dependency I had the following errors:

Downloading: ->
    http://repo1.maven.org/maven2/javax/transaction ->
      /jta/1.0.1B/jta-1.0.1B.jar
[WARNING] Unable to get resource from repository central ->
    (http://repo1.maven.org/maven2)
...
[INFO] Failed to resolve artifact.

required artifacts missing:
 javax.transaction:jta:jar:1.0.1B

This happened because Spring has a transitive dependency with the Sun’s JTA classes, but the JTA jar can’t be inserted in the Maven repository because the Sun’s Binary License.

For solving this dependency you have to download the jta-1_0_1B-classes.zip file from the Sun’s site and install it into your local repository using the following command:

mvn install:install-file \
  -Dfile=./jta-1_0_1B-classes.zip \
  -DgroupId=javax.transaction \
  -DartifactId=jta -Dversion=1.0.1B \
  -Dpackaging=jar
