[Openkm 4.1 ] Errors while compiling source

[blindrood]

When I choose to compile source of OpenKM 4.1 under Windows I get this warning

Code: Select all

[WARNING] Using platform encoding (Cp1250 actually) to copy filtered resources, i.e. build is platform dependent!

under Linux error is the same but with UTF8 encoding.

How can I resolve this warning?

[jllort]

We'll must change project configuration.

Now:
1- select project ( navigator view or other)
2- go to properties ( right click -> menu )
3- select properties
4- Change text file encoding from default container to UTF-8 ( that's the correct project codification )

Hi again, while working on OpenKM project sources, while compiling it I often get following output

It takes some time to finish but finally compilation always had succeeded. I just have no idea why this appears

[jllort]

It's GWT warning. GWT says it's better you forward by RPC known objects not de Object class ( but in this case is needed, it's a map that contains objects and then is make a instanceof )

Do you've got it in Main.gwt.xml ( might hidden this warnings )

Code: Select all

<!-- Supress compilation warnings -->
<set-property name="gwt.suppressNonStaticFinalFieldWarnings" value="true"/>

From OpenKM 5.0 we're finishing a new way to make modulable plugin in OpenKM rehusable between versions. And more configurable UI, hidden panels, buttons, etc...

[blindrood]

Yes, I have it set to true.
I'll just ignore these warnings as they seem to be harmless.

[jllort]

Really it's what I said, are only warning ... GWT says can not optimize code as it wants ... with Object class GWT can not optimize RPC call ... that's the warning.

It's strange to see the warning with that entry in Main.gwt.xml ... don't worry it's not important.

Recently I noticed strange error at DocConverter.java
I Never modified this file and any file from es.git.openkm.util
http://img27.imageshack.us/img27/1899/javadoc.png
What's more strange this error appears even with fresh source from svn
I've been ignoring this error for time when I tried to upload file to openkm compiled by me(note that my compilation did not include any changes).
I got error getDocumentChilds. Here's log
http://paste.ideaslabs.com/show/ugpk6aXET
then, after JBOSS restart I got the same error while loggin into openkm.
http://paste.ideaslabs.com/show/QHlU2e5XLo

Maybe there's something wrong with my JVM, but I don't know what.

When I replace JBoss with a new one I can log into OpenKM and use it as long as i don't try to upload something cause then it breaks again

[pavila]

Can you details the steps to reproduce the compilation error? I have downloaded the OpenKM 4.1 source code from svn and compiles ok.

[blindrood]

unfortunately(or fortunately) I can't. I got new machine with win7, prepared project and after integrating entagged audioformats and jodconverter to maven, for the first time I see openkm project folders with ZERO errors.
but.. during compilation I get info that jodconverter and audioformats are missing pom files (incorrect installation?)

Code: Select all

15.07.10 15:22:07 CEST: Build errors for openkm; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:buildnumber-maven-plugin:1.0-beta-3:create (default) on project openkm: An error has occurred while checking scm status.

15.07.10 15:20:31 CEST: [WARN] Missing POM for entagged.audioformats:audioformats:jar:0.15

can You upload those files so I can be sure there won't be any errors?

[jllort]

take a look at ext-libs !

[blindrood]

I installed entagged audioformats by command provided with file inside ext-libs(and jodconverter by modifing this command)
installation was succesfull but then 'missing pom file' problem appeared.
