Create gradle plugin for ES stable plugins #90355

pgomulka · 2022-09-26T13:59:41Z

New ES stable plugins when built should have a stable-plugin-descriptor.properties file instead of plugin-descriptor.properties.
New plugins also do not use classname property in the plugin descriptor
new plugin will also scan classes and libraries for @NamedComponents and will create named_components.json file. That file contains a map of Extensible interface (like TokenizerFactory) to a map of "component name" to "className"

This commit extracts common logic from PluginBuildPlugin into BasePluginBuildPLugin so that it can also be used by StableBuildPlugin
the differences are:
classaname - used in old plugin, but not in the new one (stable)
the plugin descriptor file name - the new one has stable-plugin-descriptor.properties
dependencies - the new plugin does not need elasticsearch as a dependency.
We might want to consider if we want to add test framework dependency in the future.

a next step will be to generate named_components.json file where information about annotated plugin components which will be stored

Hey there I left some comments we should address IMO. Also we should have that full StablePluginBuildPlugin functionality in this PR otherwise adding just the skeleton doesnt add any value IMO and each PR should have a purpose. Alternatively we just contain the refactoring here without the new Plugin

build-tools/src/main/resources/plugin-descriptor.properties

 #
 # 'classname': the name of the class to load, fully-qualified. Only applies to
 # "isolated" plugins
+<% if (classname) { %>


We should put the if block around the description too IMO

    public GeneratePluginPropertiesTask(ProjectLayout projectLayout) {
-        setDescription("Generate " + PROPERTIES_FILENAME);
-        getOutputFile().convention(projectLayout.getBuildDirectory().file("generated-descriptor/" + PROPERTIES_FILENAME));
+        // TODO I cannot tell if this is stable or not..


To be honest I would just change it to a generic description like. "Generates Elasticsearch Plugin descriptor files"

            implementationClass = 'org.elasticsearch.gradle.plugin.PluginBuildPlugin'
        }
+        stableEsPlugin {
+          id = 'elasticsearch.stable_esplugin'


our given convention is to use - instead of _ so it should be elasticsearch.stable-esplugin

It should be StableBuildPluginPlugin really as we have also a Build Plugin and that would be confusing

    }

    Map<String, String> getPluginProperties() {
-        Path propsFile = file("build/generated-descriptor/plugin-descriptor.properties").toPath();


That seems not required anymore as we split the tests of Stable Plugin Build Plugin and and Build Plugin.

In general the test that test functionality that moved into the BasePlugin should be moved into a BasePluginBuildPluginFunc test

but I cannot really test basePluginBuildPlugin without applying 'elasticsearch.esplugin' or elasticsearch.stable-esplugin`.

you can apply the BasePluginBuildPlugin just by using the classname

plugins.apply(org.elasticsearch.gradle.plugin. BasePluginBuildPlugin)

We do something similar to test internal plugins. see AbstractGradleInternalPluginFuncTest

can we use anything from groovy to compile? maybe localclasses? bytebuddy?

Not with the same convenience I guess as you can load groovy classes from a string, but you require writing it back to a jar as far as I understand?

yes, I would have to get their byte code to write them to jar. Let's keep the InMemoryJavaCompiler here for now?

Usually a classpath property is the classpath required to run the GenerateNamedComponentsAction. I wonder if its needed at all. We probbaly can merge this with pluginClasses can't we?

any views on this? is this possible?

I don't see how this is possible. We run into a chicken egg problem here

We really do not want java classes in src/(main test)/groovy as joint compilation is ridicolous slow. You can either just rename those classes to groovy or can you move them into testFixtures/java? Ultimately they are test fixtures aren't they?
