当 运行 测试反对 Arquillian 自由管理时，OpenLiberty 启动冻结

Question

示例项目是here。

Openliberty 20.0.0.1 AdaptOpenJDK 8

arquillian liberty 管理配置文件的配置。

                </plugins>
            </build>
        </profile>

和arquillian.xml文件内容：

    <container qualifier="liberty-managed">
        <configuration>
            <property name="wlpHome">target/wlp/</property>
            <property name="serverName">defaultServer</property>
            <property name="httpPort">9080</property>
            <property name="serverStartTimeout">300</property>
        </configuration>
    </container>

当运行通过以下命令进行测试：

mvn clean verify -Parq-liberty-managed

并从控制台获取信息。 Github 操作构建日志可以在 here.

中找到

看了liberty-managed的代码，找到了原因。 liberty-managed 不会从 src/main/liberty/config（就像 liberty maven 插件所做的那样）或测试中读取 server.xml类路径。它只从服务器配置文件夹又名 /usr/servers/ 读取 server.xml 文件。

但是在 liberty arquillian 项目中没有文档和示例来解释这个。

在/src/test/下创建一个自由管理的特定文件夹，命名为arq-liberty-managed，移动server.xml,arquillian.xml(复制一份)进去.

在我的 arq-liberty-managed 配置文件中，添加测试资源配置。

<build>
    <testResources>
        <testResource>
            <directory>src/test/arq-liberty-managed</directory>
            <includes>
                <include>*</include>
            </includes>
            <excludes>
                <exclude>server.xml</exclude>
            </excludes>
        </testResource>
        <testResource>
            <directory>src/test/arq-liberty-managed</directory>
            <includes>
                <include>server.xml</include>
            </includes>
            <targetPath>
                ${project.build.directory}/wlp/usr/servers/defaultServer
            </targetPath>
        </testResource>
    </testResources>
