将 kjar 部署到 jBPM/KieServer 时出错
Errors when deploying kjar to jBPM/KieServer
我一直在评估 jBPM workbench 和 KieServer 以自动构建和部署规则，但我一直坚持我做错了什么。我的目标是在最少的人工干预下构建 jar 并将其部署到 KieServer，我已经完成了以下工作：
从 https://hub.docker.com/r/jboss/jbpm-server-full 启动了一个 Docker 容器。我能够在 Workbench 中创建和部署项目 - 但我们的工作流程还将包含在 Workbench 之外构建的规则。如果一切看起来有用，我将只部署 Kie 服务器，但我只是在评估阶段。
创建了一个简单的规则项目，具有单个数据对象和规则（使用 Workbench 从成功部署中直接复制，并修改了包名称以防止可能的冲突）和我的 settings.xml 使用正确的凭据和以下 pom.xml

使用 mvn clean package deploy 构建项目 -
该项目的构建没有错误，并且显然已成功被服务接受。我可以在 Docker 实例中看到 jar，在 /opt/jboss/wildfly/bin/repositories/kie/global/com/example/rules/1.0.0-SNAPSHOT

尝试使用 http://localhost:8080/kie-server/services/rest/server/containers/test PUT API（使用正确的凭据）创建容器，但出现以下错误

- 试图在 Workbench 中创建部署单元。我可以在列表中看到该包并且可以 select 它，但是我第一次这样做时，我收到以下错误（它在单行文本框中几乎不可见 - 为了清楚起见，我已经对其进行了格式化。这是一个selection的几行出来大约600)

看起来我已经正确地执行了所有步骤（据我所知）- jar 已构建，已部署到 /opt/jboss/wildfly/bin/repositories/kie/global/ 目录，在 Workbench 中可见。但它不能作为容器部署在 KieServer 中。有人对我做错了什么有任何提示吗？
我在我的项目中发现了一个错误。我不小心将 maven/pom.properties 从另一个项目复制到我的 META-INF 目录中，该目录具有与我正在构建的 jar 不同的 groupId 和 artifactId。这导致服务器将 jar 部署到错误的 /opt/jboss/.m2/repository 位置，因此得到 GAV 'com.example:rules:1.0.0-SNAPSHOT' not found in the Maven repository. Are you sure you want to deploy it?
