Run plugings in debug mode from IDE

Spark Spark Support
4

Hello. I’m very nice that my quanstion was take in attension.
Some time later, while studying the code in search of a solution, I found it in the PluginManager.java line 286 is a hint of what I want, but I was wrong - it didn’t do what I want to see – doesn’t work.
But I didn’t give up.
As result I understood that here me necessarily need using jar file of the for plugin which i want debug, but i don’t want constantly relocate in ~/.Spark/plugins. So I still studing code and solve make next :
APPROACH 1 (but my solve – is only temprery solution in achive my goal as soon as possible)

  1. Build jar file something plugin (for exmaple meet plugin) in directory meet\target\plugins

Before building in meet\pom.xml I specify

   <properties>
        <jar.file.path>${project.build.directory}/plugins</jar.file.path>
    </properties>


<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <outputDirectory>${jar.file.path}</outputDirectory>
                </configuration>
</plugin>

${project.build.directory}/plugins == is C:\Users\User\IdeaProjects\Spark\plugins\meet\target\plugins

  1. Specify in VM options:
    -Dappdir=C:\Users\User\IdeaProjects\Spark\plugins\meet\target
  2. Run Spark in debug mode. There plugin-jar file will be relocated from ${project.build.directory}/plugins to ${env.APPDATA}\Spark\plugins. Also there check oldfile and newfile on checksum. PluginManager.java line 196 – it nice!

APPROACH 2 (does the same thing you suggest)

  1. Before building in meet\pom.xml I specify
    <properties>
        <jar.file.path>${project.build.directory}</jar.file.path>
        <spark.plugins.dir>${env.APPDATA}\Spark\plugins</spark.plugins.dir>
    </properties>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <outputDirectory>${jar.file.path}</outputDirectory>
                </configuration>
            </plugin>
            <!-- Delete the plugins directory before copying -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-antrun-plugin</artifactId>
                <version>3.1.0</version>
                <executions>
                    <execution>
                        <id>clean-and-copy-jar</id>
                        <phase>package</phase>
                        <goals>
                            <goal>run</goal>
                        </goals>
                        <configuration>
                            <target>
                                <!-- Delete the plugins directory -->
                                <delete dir="${spark.plugins.dir}" />
                                <!-- Create the directory -->
                                <mkdir dir="${spark.plugins.dir}" />
                                <!-- Copy the JAR -->
                                <copy file="${project.build.directory}\${project.build.finalName}-spark-plugin.jar"
                                      tofile="${spark.plugins.dir}\${project.build.finalName}-spark-plugin.jar"/>
                            </target>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

Run mvn that buld jar file. Now jar-plugin located in ${env.APPDATA}\Spark\plugins. But before relocate jar file I need delete content from ${env.APPDATA}\Spark\plugins that remove old version plugin but is not very good because delete all content from folder Spark\plugins.

  1. Specify in VM options:
    I didn’t specify anything here.
  2. Run Spark in debug mode.
    As result I achive my goals, but I know that presented two approuch don’t finally currect solution maybe.
    I think creating a task for this would be a good idea.
    Also I want to ask: Is it possible to add slf4j to the project because now logger it don’t convenient?
    to enable the logger, I specify in VM options: -Ddebug.mode -Ddebugger=true
