——————————————————————————————————

Install the Eclipse plugin manually

Extended Installation
1. Create a new links path under the Eclipse installation path (that is, the Links folder)
2. Create a Xxx.link file within the Links folder (it is usually recommended that the file's primary filename is the same as the plugin name and the filename suffix is. link)
3. Edit the contents of the Xxx.link,
Path=<pluginpath>
Path= is a fixed,<pluginpath> that is the extension of the plugin installation path.
4. Create a new Eclipse folder in the <pluginPath> path in the Xxx.link file and create a plugins within the Eclipse folder
and the Features folder.
5. Copy the contents of the plugins and features folders contained in the plugin into the plugins and features folders created above.
Restart Eclipse to complete the installation.
The extended installation method allows each plugin to be placed in a separate folder, so the structure is very clear. If you need to uninstall a plugin, simply add the plugin
The corresponding link file can be deleted.

Installation and use of ant

Ant is a Java-based build tool, so it has cross-platform capabilities, and the Ant tool uses XML files to write build files,
Therefore, it has better adaptability.
Because Ant has cross-platform features, you may lose some flexibility when writing ant makefile. To compensate
This deficiency, Ant "exec" core task, this task allows the execution of commands on a particular operating system.

In effect, it is somewhat similar to the Make tool in C-programming (Unix/linux), which often uses the make tool to manage
Compilation, generation of the entire project.
Make uses shell commands to define build tasks and define dependencies between tasks so that they are always executed in the necessary order.
The Make tool's generated file format is more rigorous and prone to errors.

The Make tool has the following two defects
The essence of the 1.Make tool is still dependent on the UNIX platform's shell language, so make tools cannot cross-platform
The 2.Make tool's generated file format is more rigorous and prone to errors

This shows that ant is the Make tool in the Java World, and this tool is cross-platform and has simple, easy-to-use features.

Ant's Download and installation

1. Log in to the http://ant.apache.org/bindownload.cgi site to download the latest ant version
Recommended Windows platform Download *.zip compressed package

2. Compress the downloaded compressed file to (G:software\ant1_9)
It is recommended that you rename the Ant folder to Ant199 to make it easier to find.

The 3.Ant operation requires the following two environment variables
Java_home
Ant_home: The environment variable should point to the ant installation path
G:\software\Ant1_9\Ant199

4. Allow the operating system to recognize the Ant.bat command under the%ant_home%\bin path
Add the%ant_home%\bin path to the operating system's path,

5. Start the Command Line window, enter the Ant.bat command, if prompted by the following, the ant installation is successful

C:\users\fek>ant.bat
Buildfile:build.xml does not exist!
Build failed

Installation and use of MAVEN

MAVEN is a more advanced project management tool than Ant, which employs a "Convention better than configuration (COC)"
Policies to manage the project. It is used not only to construct the source code into a project that can be published (including compiling, packaging, testing
and distribution), you can also generate reports, generate Web sites, and so on. In some ways, maven is superior to ant, so
Many companies are starting to use MAVEN.

Download and install Maven

1. Log in to the http://maven.apache.org/download.cgi site to download Maven's latest version.
Recommended Windows platform Download *.zip compressed package

2. Unzip the downloaded compressed file to any path (recommended: G:\software\Maven3_5)

3. Rename the apache-maven-3.5.2 to Maven352

The 4.Mavern operation requires the following two environment variables
Java_home: The installation path to the JDK
M2_home: Point to Maven installation path G:\software\Maven3_5\Maven352

The key command for the 5.Maven tool is the Mvn.vat command under the%m2_home%/bin path, if the reader wants the operating system to recognize the
command, you can also add the%m2_home%/bin path to the operating system's PATH environment variable. 6 Start the Command Line window and enter the following command: MVN help:system

6. If you can see that Maven is constantly downloading various files from the network and then finally displaying the following information, the MAVEN installation is successful
