Just change the following values at  eclipse ini  file to the following   -Xms1024m -Xmx2048m   Note    You can find the  eclipse ini  file by right click eclipse icon on and select  Open file location   This error occurs because the eclipse is running out of memory  so we just increased the assigned memory for the eclipse application

Check your Project -  Properties -  Java Build Path has JDK Library instead of JRE System Library  Go to Eclipse installed directory  Search eclipse ini -  Open it   Search lines for containing any below values      -Xms512m   -Xmx512m   -Xms1024m   -Xmx1024m   -Xms1G   -Xmx1G   Just double it the memory size  Assume you have to change the      -Xms512m to -Xms1024m   Increasing the eclipse memory size will help eclipse to gain more RAM size from your PC

Just delete the  metadata on workspace  and restart  IDE and configure it again properly

Close all open projects and exit Eclipse  Now you can open Eclipse without getting the error  Start opening your projects one by one to find which one causes the problem  This is most likely because you deleted a Device profile inside the AVD manager  Or you can start working on a new workspace   i e  change your workspace   then try to import your project from the old workspace

In my case  I had two of three projects with this problem in my current workspace  I opened workspace catalog and made a backup of corrupted projects  deleted them afterwards  Then opened eclipse once again  Obviously there was missing data to work with  Closed eclipse once again and added back earlier saved projects without metadata catalogs   TL DR  Just remove metadata catalogs from projects in your workspace

User · Answer

check the Eclipse log  the intelligently named   log  file in your workspace  metadata folder  and  check for the complete stacktrace  In my case it was caused at method  org eclipse m2e jdt internal MavenClasspathVariableInitializer initialize MavenClasspathVariableInitializer java 30   which lead to a never fixed  race condition during startup  bug  I would really recommend dumping Eclipse in favor of a more serious IDE  like IntelliJ or Netbeans  Using Eclipse means that you will invest 40-50  of your time trying to work around this kind of bugs  instead of being productive
