Create timers process

https://github.com/Activiti/Activiti/blob/activiti-5.22.0/modules/activiti-webapp-rest2/src/main/resources/createTimersProcess.bpmn20.xml

Activiti Diagram Editor ではこんな感じでした。

↓これを追加したらいけました。

参考: メモ：mavenでspring-mvcを利用したら、ClassNotFoundException

パスを /activiti-webapp-explorer2 → /activiti-explorer

Web Project Settings から Context root を変更します。

そのあと Server を削除して作り直したら反映されます。

なんかこう .settings フォルダーの中身がよくわからなくなって、

自分で Project Facets を再構築すると、

今度は Web Deployment Assembly の中身が不足していることがあります。

プロジェクトを削除して、

.settings フォルダーの中身を一掃して、

プロジェクトをインポートしたらいける場合があります。

Eclipse: Server Tomcat v8.5 Server at localhost failed to start.

Tomcat が起動できない…

色々修正したので詳しくはわかりません。

pom.xml で、org.spring 関係の dependency の version で、managed version との不一致が多数ありました。それらを managed version に倣うように修正したと思います。

↓こういう感じです。
Overriding managed version 1.2.6.RELEASE for spring-boot-starter-test pom.xml

<version>${spring.boot.version}</version> をまるごと削除します。

[SetContextPropertiesRule]{Context} Setting property 'source' to 'org.eclipse.jst.jee.server:activiti-webapp-explorer2' did not find a matching property.

Eclipse で Tomcat を開始すると、Console につぎのような表示が:

[SetContextPropertiesRule]{Context} Setting property 'source' to 'org.eclipse.jst.jee.server:activiti-webapp-explorer2' did not find a matching property.

server.xml につぎのような内容が書かれています。

<Context docBase="H:\Dev\workspace.jbpm\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\activiti-webapp-explorer2" path="/activiti-webapp-explorer2" reloadable="false" source="org.eclipse.jst.jee.server:activiti-webapp-explorer2"/>

どうやら無視してもよいようです。http://stackoverflow.com/a/2196889

Eclipse がデバッグ用に勝手につけている情報で、Tomcat では認知していませんよ、ということみたいです。
