概要

@umed0025さんのeclipse4.5(mars)以降でdjunitプラグインを使う方法と似た内容ですがこちらはJava15、Eclipse2021-03でdjUnitを使う方法です。

動作環境

・Ubuntu 20.04.1 LTS
・Eclipse IDE 2021-03 R Packages for Enterprise Java and Web Developers Linux x86_64（日本語化せず）
・Java15（Eclipse 2021-03に内蔵）
・djunit 0.8.6

手順

Create a ProjectでPlug-in Projectを選び枠組みを作ります。
djUnitのサイトからjp.co.dgic.eclipse.jdt.djunit_3.5.x_0.8.6.zipをダウンロードし、解凍して図で選択されているファイルを自分のプロジェクトにコピーします。
zipに含まれているdjunit-src.zipからcomとjpフォルダを自分のプロジェクトのsrcフォルダにコピーします。そして以下のファイル以外削除します。
Java15で動作させるのに必要なasm-9.1.jarファイルをここからダウンロードし、libフォルダに格納します。
META-INF/MANIFEST.MFを開きOverviewタブの以下の値を書き換えます。

設定箇所	値
ID	jp.co.dgic.eclipse.jdt.djunit
Version	0.8.6
Name	%pluginName
Activator	jp.co.dgic.eclipse.jdt.internal.junit.ui.DJUnitPlugin
Activate this plug-in when one of its classes is loaded	オン
This plug-in is a singleton	オン

見た目は以下のとおりです。

プロパティファイルの配置を変更します。
・プロジェクト直下にOSGI-INF/l10nフォルダを作成
・plugin.propertiesとplugin_ja.propertiesを上記のフォルダに移動
・MANIFEST.MFに「Bundle-Localization: OSGI-INF/l10n/plugin」を追記
Dependenciesタブを設定します。
・plugin.xmlの<requires>~</requires>に記述されている依存プラグインを追加します。※検索しても出てこないものは無視してください。
Runtimeタブを設定します。
Classpathにlib/jcoverage-djunit-1.0.5.jar、lib/jakarta-oro-2.0.7.jar、lib/asm-9.1.jar、djunit.jarを追加します。
Buildタブを設定します。
古いasmにあってasm-9.1.jarに存在しないクラスを自前で追加します。
パケージ：org.objectweb.asm
クラス：ClassAdapter、MethodAdapter

plugin作成
以上の作業が終わったらOverviewタブのExport Wizardを押下し、DesticationにDirectoryなど指定してjarを生成します。
pluginインストール
生成したjarをEclipseのpluginsフォルダにコピーし、Eclipseを再起動します。
プロジェクトのPropertiesで図のようにdjUnitが表示されていればインストール成功です。
テスト実行
AntでdjUnitタスクを実行する方法に書いたテストを実行してみます。

うまくいったようです。
