Custom maven plugin development – plugin execution not covered by lifecycle configuration

· · Leave a Comment

You are creating a custom maven plugin, everything works but when it comes to using it in a maven module inside Eclipse, m2eclipse plugin cries with message – “plugin execution not covered by lifecycle configuration”.

Now one could find a lot of documentation on how to get around with this error while using a third-party plugin, but what about if you yourself are creating a maven plugin. You would like to fix it before it comes in front of your custom-plugin users.

I was very confused with the existing documentation on how to fix it. So now as finally I fixed it, let me share it with you and come to the point.

QuickTip : Github Multiple Accounts Access with ssh

· · Leave a Comment

Let’s say we have two github accounts named “shrikant-home” and “shrikant-work”.

I would like to access both accounts from ssh.

I hope you have already created public and private keys for both github accounts and added in the ssh settings as mentioned at http://help.github.com/mac-set-up-git/

Now create a file named ~/.ssh/config file and make following entries

QuickTip : Editing Gradle Scripts with Textmate

· · Leave a Comment

You need to associate ‘.gradle’ extension with groovy as follows:

  • First if not done already, install groovy textmate bundle from http://groovy.codehaus.org/TextMate
  • In Textmate, open “Bundles –> Bundle Editor –> Edit Languages –> Groovy” and change as follows:
    [groovy]
    fileTypes = ( ‘groovy’, ‘gvy’);
    [/groovy]
    to
    [groovy]
    fileTypes = ( ‘groovy’, ‘gvy’, ‘gradle’ );
    [/groovy]

In order to run gradle scripts from Textmate use bundle from https://github.com/alkemist/gradle.tmbundle

QuickTip : WordPress Freemind Viewer Plugin – Align to Left

· · Leave a Comment

For my one of the blogs TDD Nuggets I used Freemind Viewer plugin which worked really well. However it had one annoying issue. The mindmap was somehow was not aligned to left. Because of that the whole mindmap was not visible and one has to drag it on the page to see it fully. That itself was a big hindrance to usability.

In order to display Flash based mindmap, following change was required in wp-freemind/wp-freemind.php plugin file and it finally worked.

[javascript]
<!–
var fo = new FlashObject("/wp-content/plugins/wp-freemind/visorFreemind.swf", "visorFreeMind", "100%", "100%", 6, "#9999ff");
fo.addVariable("initLoadFile","’.$content.’");
fo.addVariable("offsetX","left");
fo.write("’.$id.’");
//–>
[/javascript]

In above mentioned snippet, line 4 is added in order to set “offsetX” FlashObject variable.

QuickTip : Maven Surefire plugin – Unsupported major.minor version 51.0

· · 4 Comments

Recently I tried using JDK-7 for one small Java project with Maven and I faced issues in surefire plugin:

[bash]
[INFO] Surefire report directory: /Users/shrikant/code/eclipse-to-maven/target/surefire-reports
org.apache.maven.surefire.booter.SurefireExecutionException: com/shri/eclipsetomaven/ClasspathToPomConverterTest : Unsupported major.minor version 51.0; nested exception is java.lang.UnsupportedClassVersionError: com/shri/eclipsetomaven/ClasspathToPomConverterTest : Unsupported major.minor version 51.0
java.lang.UnsupportedClassVersionError: com/shri/eclipsetomaven/ClasspathToPomConverterTest : Unsupported major.minor version 51.0
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631)
at java.lang.ClassLoader.defineClass(ClassLoader.java:615)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141)
[/bash]

Just to make sure I used following maven-compiler-plugin configuration for JDK-7 in my pom.xml. However my build still failed.

[xml]

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
<showDeprecation>true</showDeprecation>
<showWarnings>true</showWarnings>
<executable>${env.JAVA_HOME_7}/bin/javac</executable>
<fork>true</fork>
</configuration>
</plugin>
[/xml]

Surefire plugin doesn’t seem to use this configuration for compiling test cases. By default it uses the default JDK used to run the build. In my case it was JDK-6. To make it run on new JDK, I made following changes and eventually it worked.

[xml]
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<jvm>${env.JAVA_HOME_7}/bin/java</jvm>
</configuration>
</plugin>
[/xml]
