This article has participated in the activity of “New person creation Ceremony”, and started the road of digging gold creation together.
Environment description Windows 10 i5-4460 3.2Hz 16G mvnd-0.7.1- Windows -amd64 jdk1.8Copy the codeIntroduction to the
MVND is a faster maven-based build tool based on gradle and Takari.
For more information, check out github.com/apache/mave…
The installation
Download MVND
Enter the github.com/apache/mave…
I downloaded mVnD-0.7.1 – Windows-amd64.zip
After downloading, find a path and decompress it
configuration
Configure the JDK
Since MVND relies on JDK startup, we need to configure the JDK first
Let’s look at the error log first
> mvnd clean Exception in thread "main" java.lang.IllegalStateException: Could not get value for Environment.JAVA_HOME from any of the following sources: value: java.home, environment variable JAVA_HOME, property java.home in E:\workspace\traffic_stat_backend.mvn\mvnd.properties, property java.home in C:\Users\Administrator.m2\mvnd.properties, Property Java. Home in D: \ Java \ MVND - 0.7.1 - Windows - amd64 \ conf \ MVND properties, system property java.home at org.mvndaemon.mvnd.client.DaemonParameters$EnvValue.couldNotgetValue(DaemonParameters.java:596) at org.mvndaemon.mvnd.client.DaemonParameters$EnvValue.lambda$orFail$8(DaemonParameters.java:573) at org.mvndaemon.mvnd.client.DaemonParameters$EnvValue.get(DaemonParameters.java:606) at org.mvndaemon.mvnd.client.DaemonParameters$EnvValue.asPath(DaemonParameters.java:629) at org.mvndaemon.mvnd.client.DaemonParameters.javaHome(DaemonParameters.java:140) at org.mvndaemon.mvnd.client.DaemonConnector.connect(DaemonConnector.java:99) at org.mvndaemon.mvnd.client.DefaultClient.execute(DefaultClient.java:272) at org.mvndaemon.mvnd.client.DefaultClient.main(DefaultClient.java:118)Copy the codeAn exception tells us that the configuration file java.home and the environment variable JAVA_HOME are not found
So let’s do some configuration based on this error. The way is very simple, I have listed two options here, we just need to choose the one that works best for us
The first is based on environment variables
The second method is based on MVND profile
1. Environment variable method
Note: MVND requires the environment variable JAVA_HOME or an error will be reported
I will not list the specific configuration methods here.
2. Configuration file method
In some cases, we need to configure JDK11 or higher in the environment variable, and MVND needs JDK1.8?
In this case, we can use the second method, see the instructions below
Alternatively, you can manually specify the JDK path in the Mvnd-0.7.1 -windows-amd64\conf directory
First we open the mvnd.properties file
Go to the java.home line, about line 149, and uncomment (#), then fill in the JDK path
After the modification, we execute the command again, and we can see that it has been successfully executed
mvnd clean
Copy the code
We’ll test it after we save it
Set the MVND environment variable
After setting the MVND environment variable, we can use the MVND command in any directory, the specific configuration is not listed.
Set the maven configuration built into MVND
MVN directory is MVND built-in Maven, and the use of maven is the same
To configure Maven, modify settings. XML under \ MVN \conf
The specific configuration is the same as for Maven
Specify the Settings. The XML
Note: in MVND, settings. XML under MVND \ MVN \conf is not configured directly. We need to manually execute the configuration file path
First we open the MVND \conf\mvnd.properties file
Then, at the bottom, locate the Maven.Settings configuration item
We uncomment this configuration item and fill in our absolute path to MVND \ MVN \conf\settings.xml
Please see the picture for details.
Large screen system actual combat
The actual combat project has 14 projects, let’s take a look at the execution time using MVN and MVND
Disclaimer: this test only represents the actual use of personal development records, not professional, but also has a certain reference performance
Test preconditions
After each test all projects are in the installed state (that is, after the MVN clean install command is executed)
Settings. XML is configured in the same way
The system performance
This test machine is the company’s real development machine, and the load is real
Test objectives
Run the following commands twice
mvn clean install&mvnd clean installmvn clean package&mvnd clean package
The test results

MVND faster than MVN
The problem
- Can it completely replace MVN?
- How do I replace tools such as IDEA with MVND?
- HXDS think so? Let’s talk in the comments below!
