This action provides the following functionality for GitHub Actions runners:

• Downloading and setting up a requested version of install4j
• Caching downloaded JRE bundles

After setting up install4j, its bin directory will be added to PATH, so you can run commands like createbundle or install4jc directly.

Note that by default the install4j is installed to a major-version-dependent directy like /opt/install4j10, but this action installs the install4j to a major-version-independent directory so that your build script doesn’t need to worry about which install4j version is installed to what directory. Specifically, the installation directory for each platform is as follows:

• Linux: /opt/install4j
• macOS: /Applications/install4j.app
• Windows: C:\Program Files\install4j

steps:
  - uses: luangong/setup-install4j@v1
    with:
      version: 10.0.4
      license: ${{ secrets.INSTALL4J_LICENSE }}

Currently, install4j v9 and newer are supported.

Also note that you need to specify the exact version number of install4j. Semantic version numbers such as 10.x will be supported in a future release. For the list of all available versions please refer to this page.

If you’re using Maven and the install4j Maven plugin to build your project, you can specify the installation directory of install4j in pom.xml like this:

<pluginRepositories>
  <pluginRepository>
    <id>ej-technologies</id>
    <url>https://maven.ej-technologies/repository</url>
  </pluginRepository>
</pluginRepositories>

<build>
  <plugins>
    <plugin>
      <groupId>com.install4j</groupId>
      <artifactId>install4j-maven</artifactId>
      <version>10.0.4</version>
      <executions>
        <execution>
          <id>generate-installer(s)</id>
          <phase>package</phase>
          <goals>
            <goal>compile</goal>
          </goals>
          <configuration>
            <installDir>/opt/install4j</installDir>
            <!-- Other configuration options go here -->
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

You can also specify the install4j installation directory on the command line:

mvn -Dinstall4j.home=/opt/install4j package

• Handle semantic version specifications
• Implement caching of downloaded JREs
• Take advantage of tool cache
• Cleaning up
