The project actions take a long time.

This article contains possible solutions, if you are experiencing time of waiting in case of project actions.

Symptom 1: If you import a project for the first time, this import process takes a long time and causes some time of waiting. The import of some projects might even last over 5 minutes.

Cause: The project is using system libraries. As there is a new version of these system librarires, the system libraries are updated when the project is imported for the first time.

Solution: Keep the updated project. If you need to import the updated project again, the import process will be faster.

Symptom 2: The project actions, such as the import of projects but also the cleaning of projects, take a long time and are cause some time of waiting.

Cause: The project has been created using a Neuron Power Engineer version before 1.49.0 and the steps of the following solution have not been performed yet.

Solution so that the actions for your projects are processed more quickly:

  1. In the explorer of the operating system: Go to the folder of the project – e.g. according to this FAQ-article "How can I start the explorer of the operating system from within the development environment?".
    Repeat this step for each project that you are using.

  2. Exit Neuron Power Engineer.

  3. Per project: Open the file .project of the project in any text editor and insert the following lines into the section <natures> ... </natures>:

    <nature>org.eclipse.cdt.managedbuilder.core.managedBuildNature</nature>
    <nature>org.eclipse.cdt.managedbuilder.core.ScannerConfigNature</nature>
    Example: before inserting 
    <natures>
     <nature>org.eclipse.xtext.ui.shared.xtextNature</nature>
     <nature>org.eclipse.cdt.core.cnature</nature>
    </natures>
    Example: after inserting 
    <natures>
     <nature>org.eclipse.xtext.ui.shared.xtextNature</nature>
     <nature>org.eclipse.cdt.core.cnature</nature>
     <nature>org.eclipse.cdt.managedbuilder.core.managedBuildNature</nature>
     <nature>org.eclipse.cdt.managedbuilder.core.ScannerConfigNature</nature>
    </natures>

  4. Per project: Open the file .cproject of the project in any text editor, search for <builder  and insert the following attributes: 

    enableAutoBuild="false" enableCleanBuild="false" enabledIncrementalBuild="false"
    Example: before inserting 
    <builder id="org.eclipse.cdt.build.core.settings.default.builder.1536239278" keepEnvironmentInBuildfile="false" managedBuildOn="false" name="Gnu Make Builder" superClass="org.eclipse.cdt.build.core.settings.default.builder"/>
    Example: after inserting 
    <builder enableAutoBuild="false" enableCleanBuild="false" enabledIncrementalBuild="false" id="org.eclipse.cdt.build.core.settings.default.builder.1536239278" keepEnvironmentInBuildfile="false" managedBuildOn="false" name="Gnu Make Builder" superClass="org.eclipse.cdt.build.core.settings.default.builder"/>

  5. Save all changed files in the text editor. Close the files.

  6. Start Neuron Power Engineer with a new workspace.

  7. Import the required projects.
