Build failing on sonar


With Maven 3+ we may face some issues while running sonar code coverage for the project in surefire plugin.
Looks line may be bug in maven or surefire, can't say right now.
Here is one of the weird error I have observed
Exception in thread "main" java.lang.NoClassDefFoundError: ${surefire/jvm/args}Caused by: java.lang.ClassNotFoundException: ${surefire.jvm.args} at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at
java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247)Could not find the main class: ${surefire.jvm.args}.  Program will exit.

It took really long time and lots of effort to figure out the solution for this error.
sonar goal is expecting an argument as default but failed to get and hence its throwing error.

You will need to add one extra configuration (argLine) under build section in your pom file for surefire plugin.

Please add following section in your pom to fix this error.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <argLine>-Xmx1024m</argLine>
            </configuration>
        </plugin>
    </plugins>
</build>

Here i have just mentioned the argLine=-Xmx1024m (1GB of memory), you can add any dummy argument to make build pass.

 May be recent version of maven/surefire may have fixed this issue.

Colour formatting - Jenkins Console

Image
Jenkins is the main CI tool used in Software industry. This is the backbone tool for all CI and CD implementation, Build - release and deployment methods. With the help of 100s of plugin available around the jenkins, We can achieve so much of automation around build process including build/deployment pipeline, notification, analysis, pre and post build action etc. Jenkins has tremendous power to perform great amount of work around the core build process. Many time we write script in pre and post build action to perform many tasks which is becoming very command and necessary for automation. But the main limitation in running shell script is that it's very difficult to make it more human readable for errors and make it fancy. Today i am going to cover some steps to make the output of shell script colour formatted. Jenkins Configuration Steps First install following jenkins plugin https://wiki.jenkins-ci.org/display/JENKINS/AnsiColor+Plugin Go to jenkins configurati

Manage Docker images on local disk

Docker is very powerful containerization technique, and it is becoming famous in short time. People are adapting and containerizing their applications for deployment. Soon container become very heavy and consume too much of disk space, If you do not delete old images and layers you may soon run out of disk space. Here i am trying to cover the ways to regain the disk space consumed by docker images. Moving docker filesystem to bigger mount point. Usually docker keeps all temporary files related to image building and layers at /var/lib/docker This path is local to the system usually at root partition "/" . You can mount a bigger disk space and move the content of /var/lib/docker to the new mount location and make sym link.  This way even docker images occupy space, will not affect  your system as it will be using some other mount location. Remove Old docker images Here are few ways to remove old and unused docker images Removing stopped contai

How to migrate Parent pom from maven to gradle

Convert Maven parent/super pom to Gradle init file When you think of moving to gradle for some reason from maven, You need to take care of lot of stuff around it, You can find lot of tools and help to convert maven pom.xml to gradle build.gradle But one of the most important task as an engineer or architect would be to convert your super pom (or parent pom) in to gradle init scripts. Gradle init script provides same functionality as Maven super/parent pom. The basic difference is that you can call init script Run time As many as of them This gives us flexibility to change the init script on run time but doubt of not tracking the changes.
