如何使用liberty-maven-plugin重新部署工件? [英] How to redeploy artifact with liberty-maven-plugin?

问题描述

我的机器上正在运行IBM Liberty服务器，并想使用相应的maven插件重新部署我的WAR.

I have IBM Liberty server running on my machine and want to redeploy my WAR using corresponding maven plugin.

文档说，有一些目标，例如deploy，undeploy，install-apps.目前我正在使用

The documentation says that there are goals like deploy , undeploy , install-apps . Currently I am using

<plugin>
    <groupId>com.ibm.websphere.wlp.maven.plugins</groupId>
    <artifactId>liberty-maven-plugin</artifactId> 
    <version>1.1</version>
    <executions>
        <execution>
            <id>install-apps</id>
            <phase>install</phase>
            <goals>
                <goal>install-apps</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <serverHome>c:/my-liberty-instance</serverHome>
        <serverName>myServerName</serverName>
    </configuration>
</plugin> 

但这对我不好，因为它要求服务器实例在此之前停止.如果它正在运行-会部署一个新的WAR(代替旧的WAR)，但不会捕获新的更改.

But it's not good for me because it requires the server instance to be stopped before. If it's running - a new WAR is deployed (it replaces the old one) but no new changes are caught up.

我尝试使用deploy目标，但是一旦将WAR复制到dropins目录-它开始在console.log文件中搜索一些行，该行应指示应用程序是否已启动以及是否失败.

I've tried to use deploy goal but once it copies WAR to the dropins directory - it starts searching some console.log file for some line that should indicate if app is started and FAILS.

undeploy目标的示例:CWWKM2022E: Failed to undeploy application app-1.0-SNAPSHOT.war. The Stop application message cannot be found in console.log. 但是对于deploy，stop-server也会出现相同的消息.

Example for undeploy goal : CWWKM2022E: Failed to undeploy application app-1.0-SNAPSHOT.war. The Stop application message cannot be found in console.log. But the same message appears for deploy , stop-server .

是否有一种方便的方法可以在不需要重启服务器的情况下使用liberty-maven-plugin重新部署WAR? 我只想构建一个新的WAR-进行部署；希望服务器赶上更改，仅此而已.

Is there a convenient way to redeploy WAR using liberty-maven-plugin where I don't need to restart the server ? I just want to build a new WAR - deploy it; want the server to catch up the changes and that's it.

推荐答案

您可以使用install-apps目标在不停止自由服务器实例的情况下安装项目war文件.但是您需要使用liberty-maven-plugin版本1.3 or above，并在插件配置中包含<installAppPackages>project</installAppPackages>.

You can use the install-apps goal to install the project war file without your liberty server instance stopped. But you need to use liberty-maven-plugin version 1.3 or above, and also include <installAppPackages>project</installAppPackages> to the plugin configuration.

<plugin>
    <groupId>net.wasdev.wlp.maven.plugins</groupId>
    <artifactId>liberty-maven-plugin</artifactId>
    <version>1.3</version>
    <executions>
        <execution>
            <id>install-apps</id>
            <phase>install</phase>
            <goals>
                <goal>install-apps</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <installDirectory>c:/my-liberty-instance</installDirectory>
        <serverName>myServerName</serverName>
        <installAppPackages>project</installAppPackages>
    </configuration>
</plugin>
