Disable XML validation in Eclipse

Question

My Eclipse validates XML files every time I save a file and it takes a while to validate them  The project is created using gwt-maven-plugin   The XML files are not under any Source folder build path in Eclipse  they are auto generated by SmartGWT under src main webapp  GwtModule   sc  Also all these XML files are marked with the error  Content is not allowed in prolog  and every time I run the project I have to confirm that I want to run the project with errors though there are none  and everything works fine    I tried Suspending all Validators under Eclipse -  Window -  Preferences -  Validation but to no avail   Any idea how I can stop Eclipse from annoying me every time

The other answers may work for you  but they did not cover my case   I wanted some XML to be validated  and others not   This image shows how to exclude certain folders  or files  for XML validation   Begin by right clicking the root of your Eclipse project   Select the last item  Properties        If your browser scales this image very small  right click and open in a new window or tab     Eclipse appears to be very sensitive if you click the   Browse File     or   Browser Folder     button   This dialog needs some work  This was done using Eclipse 4 3  Kepler

In JBoss Developer 4 0 and above  Eclipse-based   this is a tad easier   Just right-click on your file or folder that contains xml-based files  choose  Exclude Validation   then click  Yes  to confirm   Then right-click the same files folder again and click on  Validate   which will remove the errors with a confirmation

Ensure your encoding is correct for all of your files  this can sometimes happen if you have the encoding wrong for your file or the wrong encoding in your XML header   So  if I have the following NewFile xml    lt  xml version  1 0  encoding  UTF-16   gt   lt bar foo  foir      gt    And the eclipse encoding is UTF-8     The encoding of your file  the defined encoding in Eclipse  through Properties- Resource  and the declared encoding in the XML document all need to agree   The validator is attempting to read the file  expecting  lt  xml     but because the encoding is different from that expected  it s not finding it  Hence the error  Content is not allowed in prolog  The prolog is the bit before the  lt  xml declaration   EDIT  Sorry  didn t realise that the  xml files were generated and actually contain javascript   When you suspend the validators  the error messages that you ve generated don t go away  To get them to go away  you have to manually delete them    Suspend the validators Click on the  Content is not allowed in prolog  message  right click and delete  You can select multiple ones  or all of them  Do a Project- Clean  The messages should not come back    I think that because you ve suspended the validators  Eclipse doesn t realise it has to delete the old error messages which came from the validators

You have two options     Configure Workspace Settings  disable the validation for the current workspace   Go to Window   Preferences   Validation and uncheck the manual and build for  XML Schema Validator  XML Validator Check enable project specific settings  disable the validation for this project   Right-click on the project  select Properties   Validation and uncheck the manual and build for  XML Schema Validator  XML Validator   Right-click on the project and select Validate to make the errors disappear
