You need to install Connector/J from source only if you want to build a customized version of Connector/J or if you are interested in helping us test our new code. To just get MySQL Connector/J up and running on your system, install Connector/J using a standard binary release distribution; see Section 4.1, “Installing Connector/J from a Binary Distribution” for instructions.
To install MySQL Connector/J from source, make sure that you have the following software on your system:
It is suggested that the latest versions available for the following software be used for compiling Connector/J; otherwise, some features might not be available.
A Git client, if you want to check out the sources from our GitHub repository (available from http://git-scm.com/downloads).

To build MySQL Connector/J from source, follow these steps:
Make sure that you have JDK 1.8.x installed.
Obtain the sources for Connector/J by one of the following means:
Download the platform independent distribution archive (in
.zipformat) for Connector/J, which contains the sources, from the Connector/J Download page. Extract contents of the archive into a folder named, for example,
Download a source RPM package for Connector/J from Connector/J Download page and install it.
Check out the code from the source code repository for MySQL Connector/J located on GitHub at https://github.com/mysql/mysql-connector-j. The latest release of the Connector/J 8.1 series is on the
release/8.1branch; use the following command to check it out:
$> git clone --branch release/8.1 https://github.com/mysql/mysql-connector-j.git
Under the current directory, the command creates a
mysql-connector-jsubdirectory , which contains the code you want.
Place all the required third-party libraries in a the directory called
libat the root of the source tree (that is, in
mysql-connector-j/lib, if you have followed the steps above), or put them elsewhere and supply the location to Ant later (see Step 5 below).
Change your current working directory to the
mysql-connector-jdirectory created in step 2 above.
In the directory, create a file named
build.propertiesto indicate to Ant the location of the root directory for your JDK 1.8.x installation with the property
com.mysql.cj.build.jdk, as well as the location for the extra libraries, if they are not in
mysql-connector-j/lib, with the property
com.mysql.cj.extra.libs. Here is a sample file with those properties set (replace the “
path_to_*” parts with the appropriate file paths):
Alternatively, you can set the values of those properties through the Ant
Going from Connector/J 5.1 to 8.0 and beyond, a number of Ant properties for building Connector/J have been renamed or removed; see Section 126.96.36.199, “Changes for Build Properties” for details.
Issue the following command to compile the driver and create a
.jarfile for Connector/J:
$> ant build
This creates a
builddirectory in the current directory, where all the build output goes. A directory is created under the
builddirectory, whose name includes the version number of the release you are building. That directory contains the sources, the compiled
.classfiles, and a
.jarfile for deployment.
For information on all the build targets, including those that create a fully packaged distribution, issue the following command:
$> ant -projecthelp
Install the newly created
.jarfile for the JDBC driver as you would install a binary
.jarfile you download from MySQL by following the instructions given in Configuring the CLASSPATH or Configuring Connector/J for Application Servers.
