Containerized micro services and service orchestration disrupted how we build and run apps

The Maven Wrapper is an excellent choice for projects that need a specific version of Maven (or for users that don't want to install Maven at all). Instead of installing many versions of it in the operating system, we can just use the project-specific wrapper script.

In this quick article, we'll show how to set up a Maven Wrapper for an existing Maven project.

There're two ways to configure it in a project, where the simplest one is to use an appropriate plugin to automate it or by applying the manual installation.

Let's use this Maven Wrapper plugin to make auto installation in a simple Spring Boot project.

First, we need to go in the main folder of the project and run this command:

1
mvn -N io.takari:maven:wrapper
We can also specify the version of Maven:

1
mvn -N io.takari:maven:wrapper -Dmaven=3.5.2
The option -N means –non-recursive so that the wrapper will only be applied to the main project of the current directory, not in any submodules.

After executing the goal, we'll have more files and directories in the project:

mvnw: it's an executable Unix shell script used in place of a fully installed Maven
mvnw.cmd: it's the Batch version of the above script
mvn: the hidden folder that holds the Maven Wrapper Java library and its properties file

With a manual approach, we can copy files and folders seen above from another project to the main folder of the current project.

Afterwards, we need to specify the version of Maven to use in the wrapper properties file located in .mvn/wrapper/maven-wrapper.properties file.

For instance, our properties file has the following line:

The wrapper should work with different operating systems such as:

Linux
OSX
Windows
Solaris
After that, we can run our goals like this for the Unix system:

1/mvnw clean install
And the following command for Batch:

1/mvnw.cmd clean install
If we don't have the specified Maven in the wrapper properties, it'll be downloaded and installed in the folder $USER_HOME/.m2/wrapper/dists of the system.

Let's run our Spring-Boot project:

1/mvnw spring-boot:run
The output is the same as for a fully installed Maven:

According to a recent report by Netcraft (a well-known Internet company that provides among other services web browser usage statistics), Apache continues to be the most widely used web server among sites and Internet-facing computers.

Additionally, Apache keeps experiencing the largest growth among the top web servers, followed by Nginx and IIS. Thus, if you are a system administrator in charge of managing Apache installations, you need to know how to make sure your web server performs at the best of its capacity according to your (or you client’s) needs.

In this post we will discuss a few tips that will help you ensure that Apache will run smoothly and be able to handle the number of requests you are expecting from remote clients.

However, please keep in mind that Apache was not designed with the objective of setting benchmark records – but, even so, it is still capable of providing high performance in almost any usage case you can possibly think of.

#1: Always keep Apache updated to its latest version
#2: If you are using a Kernel older than 2.4, consider upgrading now
#3: Choose the Multi-Processing Module (MPM) that works best for your case
#4: Allocate RAM wisely for Apache
#5: Know your applications

Fig: This a snap of Apache High CPU use. :( Misconfigured MPM.

Did you see this kind of load before? :)
