PyLucene is supported on macOS, Linux, Solaris and Windows.
PyLucene requires Python 3.x (x >= 3), or Python version 2.x (x >= 3.5), and
-Java x (x >= 8). Building PyLucene requires GNU Make, a recent version of
-[Ant](https://ant.apache.org) capable of building Java
-[Lucene](https://lucene.apache.org/java/) and a C++ compiler. Use of
+Java x (x >= 8 for PyLucene 8 and earlier, x >= 11 for PyLucene 9).
+Building PyLucene requires GNU Make and a C++ compiler. Use of
[setuptools](https://pypi.python.org/pypi/setuptools) is recommended.

## Requirements
-To build PyLucene a Java Development Kit (JDK) and [Ant](https://ant.apache.org)
-are required; use of the resulting PyLucene binaries requires only a Java Runtime
-Environment (JRE).
+To build PyLucene a Java Development Kit is required; use of the resulting PyLucene binaries requires only a Java Runtime Environment (JRE).
+A recent C/C++ compiler is also required.
+**Attention:** Starting with release 9.x, Lucene requires Java 11 or above.<br/>
**Attention:** Starting with release 6.x, Lucene requires Java 1.8.
-On macOS, you will need to install Oracle Java 8, and due to a
-[bug](https://bugs.openjdk.java.net/browse/JDK-7131356) in the JDK for macOS,
-you will **also** need to install Apple's Java 1.6.
-
-On macOS, once installed, a way to make Java 1.8 the default in your bash shell is:<br/>
-```
-$ export JAVA_HOME=\`/usr/libexec/java_home\`
-```
-Be sure to verify that JAVA_HOME value.
+On macos and linux, the [Temurin JDK](https://adoptium.net/) is recommended.
+See "Notes for Linux" at [this page](jcc/install.html) for installation instructions on Linux Debian 11.
On any system, if you're upgrading your Java installation, please rebuild
JCC as well. You must use the same version of Java for both JCC and PyLucene.

Getting the java configuration correct is important and is done differently for
every distribution.<br/>For example:
-- On Ubuntu, to install Java 5, these commands may be used:
+- On Debian 11, the commands below install Temurin Java 17, Python 3.9, gcc, g++ and make
+
+install Temurin Java (Adoptium)
```
- $ sudo apt-get install sun-java5-jdk<br/>
- $ sudo update-java-alternatives -s java-1.5.0-sun<br/>
+sudo -s
+apt install wget apt-transport-https gnupg

+install gcc, g++ and make
+```
+sudo apt install gcc-x86-64-linux-gnu g++-x86-64-linux-gnu make

+```
+sudo apt install python3.9-dev python3-venv python3-setuptools

The samples flags for Linux in JCC's setup.py should be close to correct.

-- On Gentoo, the _java-config_ utility should be used to locate, and possibly
-change, the default java installation. The sample flags for Linux in JCC's

-```
- $ java-config -O
