In Grails, the command "tomcat:deploy" does not generate the complete war as the command "dev war" does

The command "grails dev war" deploys perfectly in my local Tomcat6 server with a generated war which contains the next folders:

css
images
js
META-INF
plugins
WEB-INF

Unfortunately, I need that the command tomcat:deploy works too (I'm actually using: tomcat:redeploy -DskipTests). But Tomcat gives the next error:

2013-05-23 05:12:53,094 [http-8080-4] ERROR digester.Digester  - Parse Fatal Error at line 1 column 1: Final de archivo prematuro.
org.xml.sax.SAXParseException; systemId: jndi:/localhost/Alojamiento/WEB-INF/web.xml; lineNumber: 1; columnNumber: 1; Final de archivo prematuro.
    at

I added an empty web.xml in order to maven compiled. It is also empty in the generated war. So it is probably the cause of the problem ("grails dev war" generates a web.xml with code). Futhermore, the generated war only contains the next folders:

META-INF
WEB-INF

To be able to use "tomcat deploy", I added the next code to the pom.xml (after adding pom true, running "create-pom group" and other configuration changes):

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>
    <configuration>
        <url>http://127.0.0.1:8080/manager</url>                    
        <server>TomcatServer</server>
    </configuration>
</plugin>

解决方案

It is perfectly working with this:

CONFIGURATION

Previously, if you are using Eclipse with the plugin m2e, here is explained how to configure Eclipse in order to use Tomcat with it: tomcat-maven-plugin: Server returned HTTP response code: 403

Now, we need a proper settings.xml in the C:\Users\user.m2 with the same user and password than tomcat-users.xml. Then, we need to have our pom.xml configurated as follow:

<packaging>war</packaging>


<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>tomcat-maven-plugin</artifactId>
<configuration>
    <url>http://127.0.0.1:8080/manager</url>   
    <!-- The next server must be the same than the one in settings.xml (at C:\Users\user\.m2): -->
    <server>TomcatServer</server>
</configuration>
</plugin>   


<plugin>
    <groupId>org.grails</groupId>
    <artifactId>grails-maven-plugin</artifactId>
    <version>${grails.version}</version>
    <extensions>true</extensions>
    <executions>
        <execution>
            <goals>
                <goal>init</goal>
                <goal>maven-clean</goal>
                <goal>validate</goal>
                <goal>config-directories</goal>
                <goal>maven-compile</goal>
                <goal>maven-test</goal>
                <goal>maven-war</goal>
                <goal>maven-functional-test</goal>
            </goals>
        </execution>
        </executions>
</plugin>

MAVEN COMMANDS TO DEPLOY:

The next command get the configuration values of our database from datasource.groovy - production environmnent:

tomcat:redeploy
tomcat:redeploy -DskipTests
grails:war tomcat:redeploy -DskipTests

To get the values from the development environment, the commands are the next:

grails:war tomcat:redeploy -Dgrails.env=development grails:war
tomcat:redeploy -Dgrails.env=development -DskipTests

Note1: if we not add -DskipTests (to no running tests before to deploying), and some test fail, it won't deploy.

Note2: in eclipse (with the plugin m2e for maven installed), you have to type these commands in the next field:

Run - Run Configurations - Maven Build - Goals

UPDATE 1

Do not forget to create an empty web.xml under src/main/webapp/WEB-INF!

UPDATE 2

Do not forget to tell Grails to use the pom.xml: http://grails.org/doc/2.3.x/ref/Command%20Line/create-pom.html

其他提示

Try

mvn grails:war tomcat:redeploy -DskipTests

That should hopefully get grails to attach the correct WAR artefact to the build so that the empty default one is not uploaded.
