## 3 Installation

This chapter explains how to install the Jakarta Expression Language TCK software.

After installing the software according to the instructions in this chapter, proceed to Chapter 4, "Setup and Configuration," for instructions on configuring your test environment.

Note | Although the Expression Language 6.0 TCK is not depended on any particular build tool, it is convenient to install Apache Maven 3.6.3+ for setup and execution of tests. Any other build tools like Gradle and JUnit 5 Console Runner can also be used that is Jupiter API compatible.

### 3.1 Obtaining a Compatible Implementation

Each compatible implementation (CI) will provide instructions for obtaining their implementation. Eclipse GlassFish 6.0 is a compatible implementation which may be obtained from https://projects.eclipse.org/projects/ee4j.glassfish

### 3.2 Installing the Software

Before you can run the Expression Language TCK tests, you must install and set up the following software components:

- A Jakarta EE 11 Compatible Implementation

- Java SE 21

- A CI for Expression Language 6.0, one example is Eclipse GlassFish 6.0

- Expression Language TCK version 6.0

- The Expression Language 6.0 Vendor Implementation (VI)

- Any Jupiter API compatible test runner (eg. Apache Maven 3.6.3+)

Follow these steps:

1. Install the Java SE 21 software, if it is not already installed.
   Download and install the Java SE 21 software from http://www.oracle.com/technetwork/java/javase/downloads/index.html. Refer to the installation instructions that accompany the software for additional information.

2. Install the build tool that will be used to run the TCK, if it is not already installed.
   It will be convenient to use Apache Maven 3.6.3+ for running the tests. The test kit is not depended on Maven, any build tool compatible with Jupiter API is suffitient.

3. Install the Expression Language TCK 6.0 software.

   1. Copy or download the Expression Language TCK software to your local system.
      You can obtain the Expression Language TCK software from the Jakarta EE site https://jakarta.ee/specifications/expression-language/6.0/.

   2. Use the `unzip` command to extract the bundle in the directory of your choice:
      `unzip jakarta-expression-language-tck-6.0.0.zip`

4. Install the Jakarta EE 11 CI software (the servlet Web container used for running the Expression Language TCK with the Expression Language 6.0 CI), if it is not already installed.
   Download and install the Servlet Web container with the Expression Language 6.0 CI used for running the Expression Language TCK 6.0, represented by the Jakarta EE 11 CI. You may obtain a copy of this CI by downloading it from https://projects.eclipse.org/projects/ee4j.glassfish.

5. Install a Expression Language 6.0 Compatible Implementation.
   A Compatible Implementation is used to validate your initial configuration and setup of the Expression Language TCK 6.0 tests, which are explained further in Chapter 4, "Setup and Configuration."
   The Compatible Implementations for Expression Language are listed on the Jakarta EE Specifications web site: https://jakarta.ee/specifications/expression-language/6.0/.

6. Install the Expression Language VI to be tested.
   Follow the installation instructions for the particular VI under test.
