Payara Micro Maven Plugin

Payara Micro has a Maven plugin which can start and stop Payara Micro and create an Uber JAR bundle of the application and Payara Micro.

The plugin requires JDK 8 or higher and the latest version is currently 1.0.2

Configurable Goals

`bundle`

Aim: This goal bundles the attached project’s artifact into an Uber JAR with the specified configurations. By default this goal is attached to the install phase. Usage: mvn payara-micro:bundle

Example:

    <plugin>
        <groupId>fish.payara.maven.plugins</groupId>
        <artifactId>payara-micro-maven-plugin</artifactId>
        <version>${payaramicro.maven.plugin.version}</version>
        <executions>
            <execution>
                <goals>
                    <goal>bundle</goal>
                </goals>
            </execution>
        </executions>
        <configuration>
            <startClass>my.custom.start.class.Main</startClass>
            <deployArtifacts>
                <artifactItem>
                    <groupId>org.mycompany</groupId>
                    <artifactId>my-project</artifactId>
                    <version>1.0</version>
                    <type>ear</type>
                </artifactItem>
            </deployArtifacts>
            <customJars>
                <artifactItem>
                    <groupId>org.primefaces</groupId>
                    <artifactId>primefaces</artifactId>
                    <version>6.0</version>
                </artifactItem>
            </customJars>
        </configuration>
    </plugin>

Table 1. Configuration tags
Element	Default	Notes
`autoDeployArtifact`	true	If the extension of the produced artifact is `WAR`, it will be copied automatically to the `MICRO-INF/deploy` directory when this property is set to `true`.
`autoDeployContextRoot`	none	Sets context root of the deployed artifact if `autoDeployArtifact` is `true`. `autoDeployContextRoot` has the higher precedence compared to the `autoDeployEmptyContextRoot`.
`autoDeployEmptyContextRoot`	true	Sets context root of the deployed artifact to `/` if `autoDeployArtifact` is `true`. If set to false, context root is derived from `project.build.finalName`. If `autoDeployContextRoot` is specified, `autoDeployEmptyContextRoot` will be ignored.
`startClass`	(optional):	Replaces the `Start-Class` definition that resides in the `MANIFEST.MF` file with the provided class.
`appendSystemProperties`	true	Appends all system properties defined into the `payara-boot.properties` file.
`payaraVersion`	5.182	By default bundle mojo fetches payara-micro with version 5.182.
`deployArtifacts`	None	Can contain a list of artifactItems, which defines the dependencies with their GAVs to be copied under MICRO-INF/deploy folder.
`customJars`	None	Can contain a list of artifactItems, which defines the dependencies with their GAVs to be copied under MICRO-INF/lib folder.

`start`

Aim: This goal starts Payara Micro with the specified configuration.

Usage: mvn payara-micro:start

Example:

<plugin>
    <groupId>fish.payara.maven.plugins</groupId>
    <artifactId>payara-micro-maven-plugin</artifactId>
    <version>${payaramicro.maven.plugin.version}</version>
    <executions>
        <execution>
            <goals>
                <goal>start</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <useUberJar>true</useUberJar>
        <payaraMicroAbsolutePath>/path/to/payara-micro.jar</payaraMicroAbsolutePath>
        <payaraVersion>5.182</payaraVersion>
        <artifactItem>
            <groupId>fish.payara.extras</groupId>
            <artifactId>payara-micro</artifactId>
            <version>5.182</version>
        </artifactItem>
        <daemon>true</daemon>
        <javaPath>/path/to/Java/Executable</javaPath>
        <deployWar>true</deployWar>
        <javaCommandLineOptions>
            <option>
                <value>-Xdebug</value>
            </option>
            <option>
                <key>-Xrunjdwp:transport</key>
                <value>dt_socket,server=y,suspend=y,address=5005</value>
            </option>
        </javaCommandLineOptions>
        <commandLineOptions>
            <option>
                <key>--domainconfig</key>
                <value>/path/to/domain.xml</value>
            </option>
            <option>
                <key>--autoBindHttp</key>
                <value>true</value>
            </option>
        </commandLineOptions>
    </configuration>
</plugin>

If you want to execute the payara-micro plugin along with maven-toolchains-plugin, you need to execute the plugin as: mvn toolchains:toolchain payara-micro:start

Table 2. Configuration tags
Element	Default	Notes
`useUberJar`	false	Use created uber-jar that resides in target folder. The name of the JAR artifact will be resolved automatically by evaluating its final name, artifact ID and version. This configuration element has the higher precedence compared to `payaraMicroAbsolutePath`, `payaraVersion` and `artifactItem`.
`payaraMicroAbsolutePath`	none	Absolute path to payara-micro executable.
`payaraVersion`	5.182	By default start mojo fetches payara-micro with version 5.182.
`artifactItem`	none	Defines payara-micro artifact with its coordinates. Specified artifact should be available in local maven repository.
`daemon`	false	Starts payara-micro in separate JVM process and continues with the maven build.
`immediateExit`	false	If payara-micro is executed in daemon mode, the executor thread will wait for the ready message before shutting down its process. By setting `immediateExit` to `true` you can skip this and instantly interrupt the executor thread.
`javaPath`	`java`	Absolute path to the java executable. This has higher priority to the java executable identified via Maven toolchain.
`deployWar`	false	If the attached project is of type WAR, it will automatically be deployed to payara-micro if `deployWar` is set to `true`.
`javaCommandLineOptions`	none	Defines a list of command line options that will be passed to `java` executable. Command line options can either be defined as key-value pairs or just as list of values. key-value pairs will be formatted as `key=value`.
`commandLineOptions`	none	Defines a list of command line options that will be passed onto payara-micro.

`stop`

Aim: This goal stops Payara Micro with the specified configuration. By default this goal tries to find the currently executing Payara Micro instance by checking the running uberjar. If an artifactItem is defined, it will take precedence for identifying currently running instances. If processId is defined, this takes the highest precedence and the given processId will immediately kill the executing Payara Micro instance.

Usage: mvn payara-micro:stop

Example:

<plugin>
    <groupId>fish.payara.maven.plugins</groupId>
    <artifactId>payara-micro-maven-plugin</artifactId>
    <version>${payaramicro.maven.plugin.version}</version>
    <executions>
        <execution>
            <goals>
                <goal>stop</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <processId>32333</processId>
        <artifactItem>
            <groupId>fish.payara.extras</groupId>
            <artifactId>payara-micro</artifactId>
            <version>5.182</version>
        </artifactItem>
    </configuration>
</plugin>

If you want to execute the payara-micro plugin along with maven-toolchains-plugin, you need to execute the plugin as: mvn toolchains:toolchain payara-micro:start

Table 3. Configuration tags
Element	Default	Notes
`processId`	none	Process id of the running payara-micro.
`artifactItem`	none	Defines payara-micro artifact with its coordinates. This information is used to identify the process id of the running payara-micro.
