Maven Error - Package does not exist, Symbols not recognised

[Praneet Mirchandani]

Hi,

I am trying to build a Struts Web Application using Maven. I am getting the following errors when I run mvn compile:

1. package org.apache.struts.action does not exist
2. package org.apache.struts.util does not exist

Also getting the following unrecognised symbol errors:

1. ActionMapping, ActionForm, ActionForward, ActionErrors

2. HttpSevletRequest, HttpServletResponse

3. DynaActionForm

I tried installing the struts.jar file in the local maven repository using the command:

mvn install:install-file -DgroupId=struts -DartifactId=struts -Dversion=1.0 -Dpackaging=jar -Dfile= Path to file.

It gives the following error:
The plugin 'org.apache.maven.plugins:maven-D-plugin' does not exist or no valid version could be found.

Please help.

Thanks,
Praneet.

Try to install the jar file with the version that you have mentioned in your POM dependency.
I think these two are mismatching.

[Praneet Mirchandani]

Kousik - that did not work unfortunately.

Do you know what is the latest version of the struts jar file?

Thanks,
Praneet

[Kousik Majumder]

I think that hardly matter. What you have used in your project that only matters.
You also need to install servlet API jar. Because your error list also include that one.

[Praneet Mirchandani]

Have managed to install servlet-api.jar successfully.

Its struts.jar that is giving the problem.


Thanks,
Praneet

[Kousik Majumder]

Give the pom.xml code and full error trace.

I tried installing the struts.jar file in the local maven repository using the command:

It already available in the Maven repo. What exact errors do you get? And what does your pom.xml look like?

[Praneet Mirchandani]

Hi,

I downloaded the struts jar from the maven repository and pasted it in my local maven repository.

Pasted the following at the path - D:\Documents and Settings\praneet.mirchandani\.m2\repository\struts\struts\1.0.2

struts-1.0.2.jar, struts-1.0.2.jar.sha1, struts-1.0.2.pom, struts-1.0.2.pom.sha1.

Then I ran mvn compile. This is the error log I got:

Remove the last struts plugin:

<plugin>
<groupId>struts</groupId>
<artifactId>struts</artifactId>
<version>1.0.2</version>
</plugin>

Then run again.

[Praneet Mirchandani]

Hi Kousik,

Tried what you suggested. Now it is throwing me some more errors when I run mvn compile:

package org.apache.struts.action does not exist

package org.apache.struts.util does not exist

Unrecognised Symbols

ActionMapping, ActionForm
ActionForward, ActionErrors
DynaActionForm, DispatchAction

Thanks,
Praneet

[Praneet Mirchandani]

Hi,

I need to include a jar file I have made in order to build the project.

I think I would need to mention that in my pom.xml, but I dont know how?

I dont think it can be put in the dependency tag or the plug in tag. So where do I put it?

Thanks,
Praneet

[Kousik Majumder]

I think you have installed in wrong way.
Run the following command and install again.
I have only changed the groupid.

mvn install:install-file -DgroupId=org.apache.struts -DartifactId=struts -Dversion=1.0 -Dpackaging=jar -Dfile= Path to file

[Praneet Mirchandani]

Hi,

I tried that. It throws the following error:

The plugin 'org.apache.maven.plugins:maven-D-plugin' does not exist or no valid version could be found.


Thanks,
Praneet

[Kousik Majumder]

Sorry . I make the mistake now. make the version 2.0.6 in the command line prompt that I had written.

mvn install:install-file -DgroupId=org.apache.struts -DartifactId=struts -Dversion=2.0.6 -Dpackaging=jar -Dfile= Path to file

[David Newton]

Struts 2.0.6?!

To the original poster: please show the *exact* command you're typing, and put it inside code tags, so we can see where any spaces are. So far it just looksl ike you're not putting quotes around a path that has spaces in it, which will cause the install to fail.

You can also just *look* in the repository to see if it's there, and obviously the dependency needs to be in your POM.

To summarize:
- Post the *exact* command you're using to install, in code tags
- Check to see if it's already in the repository
- Post the POM dependency you're using.

[Praneet Mirchandani]

Sorry. Noted for next time.

I had to include a certain jar as a dependency. So I pasted it in the local repository and then ran the command below.

mvn install:install-file -DgroupId=com.wellmanage.pricing -DartifactId=PricingMigrationCoreComponents -Dversion=1.0 -Dfile= D:\Documents and Settings\praneet.mirchandani\.m2\repository\PricingCore\PricingCore\1.0\PricingMigrationCoreComponents.jar -Dpackaging=jar -DgeneratePom=true

It gave the following error:
The plugin 'org.apache.maven.plugins:maven-D-plugin' does not exist or no valid version could be found.

Tried searching a lot for this error, but could not figure out.

Thanks,
Praneet

[David Newton]

Like I said, you're not quoting a path with a space in it: the computer has no way of knowing that space isn't delimiting commands. I'd also remove the space after the "-Dfile= ".

And *don't* put it in the repository manually--put it somewhere easy (like c:\), then you don't have to worry about spaces at all.

[Praneet Mirchandani]

Hi

I managed to install the external jar. Thanks David.

But when I ran mvn compile after that, it still threw me errors saying it cannot recognise certain packages which were in the newly installed jar. Any idea why this happened?

[David Newton]

You did it wrong? Your POM dependency is wrong? The jar doesn't contain the classes you think it does?

Without knowing any details, it's impossible to help.
