dev mode in multimodule fails to restart server #1726

andre-doherty · 2023-09-19T15:37:56Z

hello,

Please let me report an issue regarding the liberty-maven-plugin.

When i try to restart a server configured in a submodule, using the 'r' key in the console, it usually fails as the plugin tries to add some features in the running server instance, which is killed as the features might be incompatible.

mvn -am -pl submodule-ws liberty:dev : launch the server which starts normally without errors
the liberty plugin is set in the submodule-ws pom.xml with the following configuration :

<groupId>io.openliberty.tools</groupId>
<artifactId>liberty-maven-plugin</artifactId>
<version>3.8.2</version>
<configuration>
	<assemblyArtifact>
	<groupId>com.ibm.websphere.appserver.runtime</groupId>
	<artifactId>wlp-javaee7</artifactId>
	<version>23.0.0.8</version>
</assemblyArtifact>
</configuration>
<executions>
	<execution>
	     <id>install-feature</id>
	     <phase>prepare-package</phase>
	     <goals>
		 <goal>install-feature</goal>
	    </goals>
		<configuration>
			<features>
				<acceptLicense>true</acceptLicense>
				<feature>jsp-2.2</feature>
				<feature>localConnector-1.0</feature>
				<feature>cdi-1.0</feature>
				<feature>jaxrs-1.1</feature>
				<feature>jpa-2.0</feature>
				<feature>jaxws-2.2</feature>
				<feature>ejbLite-3.1</feature>
				<feature>beanValidation-1.0</feature>
				<feature>transportSecurity-1.0</feature>
				<feature>jdbc-4.2</feature>
			</features>
		</configuration>
	</execution>
	<execution>
		<id>create</id>
		<phase>initialize</phase>
		<goals>
			<goal>install-server</goal>
		</goals>
	</execution>
</executions>
</plugin>

server.xml has the following features activated (matchs the pom) :

<server description="sampleapp">
    <featureManager>
        <feature>jsp-2.2</feature>
        <feature>localConnector-1.0</feature>
        <feature>cdi-1.0</feature>
        <feature>jaxrs-1.1</feature>
        <feature>jpa-2.0</feature>
        <feature>jaxws-2.2</feature>
        <feature>ejbLite-3.1</feature>
        <feature>beanValidation-1.0</feature>
        <feature>transportSecurity-1.0</feature>
        <feature>jdbc-4.2</feature>
    </featureManager>

When i try to restart i have the following error :

[INFO] Parsing the server file for features and includes: defaultServer/server.xml

It seems the plugin looses track of the actual server configuration at this point.

This pb doesnt show when invoking dev mode within the -ws submodule directory.

@andre-doherty Can you include the console messages for the initial startup? I want to compare the features it installs on initial startup vs the restart. The console messages you included show the restart tries to install the same list of features as the server.xml. So I am not sure what you meant by:

cherylking · 2023-09-19T15:51:40Z

I would like you to remove the features from the pom.xml. Just leave the acceptLicense in the pom.xml. The features should be in the server.xml and will get installed by the plugin. I believe the server is getting created by default with a server.xml that includes the javaee-7.0 feature (since you are using the wlp-javaee7 runtime) and it is trying to install that in addition to what you have in the pom.xml, and that is not compatible with all the javaee6 features.

Where is your server.xml located? Do you need to add the location to the plugin configuration in the pom.xml? If it is not in src/main/liberty/config it will not use it.

Hello @cherylking,

Everything is fine until i try to restart the server...
All configuration files are corrected picked on the first start.

Where is your server.xml located? Do you need to add the location to the plugin configuration in the pom.xml? If it is not in src/main/liberty/config it will not use it.

The server.xml is correctly found (located in the default location) : datasources, libraries are configured.

So i have tried to remove the features list in the pom, doesn't change anything.
Restart still fails.

André

andre-doherty · 2023-09-19T17:39:54Z

Actually the plugin behaves just as if there was no server.xml, as if the module name specified in the command line with the pl switch was not kept.

andre-doherty · 2023-09-26T09:29:44Z

hello @cherylking,

Do you need some more elements ?

Regards,
André

cherylking · 2023-09-26T11:54:22Z

@andre-doherty Can you provide a sample project to recreate?

Until then, I have a suggestion. Instead of using the wlp-javaee7 server when you are using Java EE 6 features, can you try using the wlp-kernel runtime artifactId instead?

andre-doherty · 2023-09-27T17:09:08Z

@andre-doherty Can you provide a sample project to recreate?

Hello @cherylking,
Here you are :
sample.zip

I have tried to minimize it as max as possible.
To reproduce :
from the parent pom run :
mvn clean install
mvn -am -pl module-ws io.openliberty.tools:liberty-maven-plugin:dev
Try to restart the server using the 'r'

Note : i am using the following :
mvn --version

Maven home: /opt/homebrew/Cellar/maven/3.9.3/libexec
Java version: 17.0.7, vendor: Homebrew, runtime: /opt/homebrew/Cellar/openjdk@17/17.0.7/libexec/openjdk.jdk/Contents/Home

cherylking · 2023-09-27T22:12:31Z

Thanks for the sample project @andre-doherty. I will try to work on this next week. Did you try the workaround?

andre-doherty · 2023-09-28T09:12:13Z

hello @cherylking,
Yes, sorry i did not give you a feedback on the suggested workaround.
It doesn't work as well, it fails also but with a different error.

You can test the fix with the 3.9-SNAPSHOT. We are targeting a release by the end of this week.

scottkurz · 2023-10-02T22:58:09Z

FWIW, just noting that I tried and failed to recreate this with Maven v3.8.8.... but I did succeed recreating on the noted v3.9.3. Thought that was interesting to observe the version-specific behavior for this Maven API.

andre-doherty · 2023-10-03T07:14:08Z

hello @cherylking, @scottkurz,

I have been able to test the version 3.9-SNAPSHOT this morning.
The defect is gone.

Thanks a lot for your action !
Regards,
André
