How to add module compile output to web-inf/classes in stead of web-inf/lib?

创建于 2015年07月14日 09:36

I'm using maven to set up a war project in

IntelliJ

and run in it

GlassFish

. The war project depends on several other modules. When I run the project in debug mode, hot deploying codechanges of the changes results in

NoClassDefFound

exceptions. I found out that

IntelliJ

tries to redeploy the module jar but

GlassFish

keeps a lock on it so it fails. All the classes in that module are now unavailable, causing these

NoClassDefFound

exceptions.

IntelliJ

generates the artifacts this way: the dependent modules are all added as jar dependencies as if they were external dependencies:

Now, when I remove the jar dependencies,

IntelliJ

tells me it found some missing dependencies and proposes a fix to add the missing dependencies.
Fixing those dependencies will add the module compile output to the

WEB-INF\classes

folder.

Once deployed,

IntelliJ

has no problem anymore hot-deploying changed classes to GlassFish since there's no jar to keep a lock on.

Problem

Every time I make a change to any

pom.xml

IntelliJ

refreshes the artifacts automatically, which is fine: I definitely want to see those changes appear in the artifact. However, all modules are added as

jar

dependencies again.

Question

How can I make sure that IntelliJ adds the compile output of project modules to

WEB-INF\classes

and not to

WEB-INF\lib

? (or: is there another way to avoid those

NoClassDefFound

errors?
I found this question but it has two problems:

There are many module dependencies so if possible I'd like to avoid specifying them all one by one in the unpack goal
```
IntelliJ
```
seems to ignore this. When I add that configuration and while it works perfectly in a maven commandline build,
```
IntelliJ
```
still refuses to add the module compile output to the
```
WEB-INF\classes
```
dir

I found a bugreport that asks about the same thing but for me it's hard to believe there's no way to solve this problem. Other webapp developers using

IntelliJ

must have this same issue, making it difficult to hot-deploy code changes, unless I did something wrong in my

pom

configuration.

I have a similar problem. Intellij compiles the classes inside target/classes, which is ok because I use maven. But I need the same classes inside WEB-INF/classes too.

Eclipse seems to be able to do this automatically, but for Intellij we use a workaround. You could use the plugin "maven-antrun-plugin" with copy function to refresh automatically the classes inside WEB-INF before launch.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.7</version>
    <executions>
        <execution>
            <phase>validate</phase>
            <goals>
                <goal>run</goal>
            </goals>
            <configuration>
                <tasks>
                    <delete dir="${project.basedir}/web/WEB-INF/classes" />
                    <delete dir="${project.basedir}/web/WEB-INF/lib" />
                    <copy todir="${project.basedir}/web/WEB-INF/classes">
                        <fileset dir="${project.basedir}/src">
                            <include name="*.*"/>
                        </fileset>
                    </copy>
                    <copy todir="${project.basedir}/web/WEB-INF/classes/de">
                        <fileset dir="${project.basedir}/target/classes/de"/>
                    </copy>
                </tasks>
            </configuration>
        </execution>
    </executions>
</plugin>
