Eclipse no arranca y no he cambiado nada

No he actualizado nada durante al menos un mes. Estaba trabajando normalmente y, de repente, los menús estaban en blanco, así que decidí reiniciar eclipse. Hice clic en "cerrar" y "ok" para guardar todo, pero no pasó nada, así que volví a hacer clic en cerrar y eclipse se cerró. Hice clic en eclipse y la pantalla de carga solo parpadea y desaparece, seguida de un mensaje que me dice que revise el .logarchivo. Desde entonces, reinicié la PC varias veces, intenté ejecutarla en modo seguro y ejecuté eclipse.exe -cleany nada funciona.

¿Algunas ideas?

Usé eclipse -clean -clearPersistedStatey eso funcionó para mí. Perderá la configuración del diseño de su ventana, pero eso me parece menor.

Para sistemas Linux, pruebe: ./eclipse -clean -clearPersistedState

Ver que Eclipse JUNO no se inicia

Ok, lo descubrí. Vaya a yourWorkspace / .metadata / .plugins y elimine todo lo que hay allí. Eclipse se iniciará y volverá a llenar la carpeta.

Eliminar workbench.xmi en workspace / .metadata / .plugins / org.eclipse.e4.workbench / funcionó para mí. No eliminó los proyectos existentes.

Esto funciona como campeón en mac os o windows.

Elimine workbench.xmi ubicado en workspace / .metadata / .plugins / org.eclipse.e4.workbench / workbench.xmi . Luego inicie su Eclipse o ADT. Esto no borrará su espacio de trabajo o repositorio.

Eliminar workbench.xmi cmd:

espacio de trabajo rm / .metadata / .plugins / org.eclipse.e4.workbench / workbench.xmi.

Tratar:

$ rm YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.core.resources/.snap

Fuente original: trabajo encontrado que aún se está ejecutando después del eclipse de cierre de la plataforma

Eliminé workbench.xmi en la carpeta workspace / .metadata / .plugins / org.eclipse.e4.workbench /.

Recibí este error porque una compilación se colgó y luego intenté salir. Sin embargo, tenía cambios sin guardar. Esto provocó los siguientes errores en el archivo de registro sobre los cambios no guardados y los trabajos que no se terminaron.

Hoy tuve el mismo problema. Mi eclipse se negó a comenzar. Cuando hice doble clic en el icono de Eclipse, pude ver la pantalla de bienvenida por un segundo y luego no pasó nada. Probé la mayoría de las soluciones aquí: archivo de bloqueo eliminado, espacio de trabajo renombrado, intenté iniciar Eclipse con diferentes parámetros limpios. Incluso puse una nueva copia de Eclispe e intenté comenzar con un nuevo espacio de trabajo. ¡Nada!

Mis registros mostraban un montón de errores de ayer cuando mi estación de trabajo se reinició a las 17:45.

!ENTRY org.eclipse.ui.workbench 4 2 2014-12-17 17:45:12.178
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
!STACK 0
java.lang.NullPointerException

Al final, este cambio muy simple (mira a continuación) salvó mi Eclipse junto con mi espacio de trabajo.

SOLUCIÓN:

Edité eclipse.iniy agregué la siguiente línea:

-vm
C:\Program Files\Java\jdk1.6.0_26\bin\javaw.exe

¡Eclipse ha comenzado de nuevo con todos mis proyectos adentro! Espero que esto pueda ayudar.

Tal vez valga la pena mencionar que cuando tuve este problema, seguí el consejo de bia.migueis: mover todo fuera de la carpeta de complementos, y el espacio de trabajo se abriría nuevamente, menos gran parte de mi configuración. Pero luego de eso, copié / sobrescribí todos los archivos originales nuevamente en la carpeta de complementos y abrí el espacio de trabajo nuevamente: todavía funcionaba y la configuración que tenía antes parecía estar intacta.

Moví workbench.xmi ubicado en workspace / .metadata / .plugins / org.eclipse.e4.workbench / workbench.xmi a una carpeta de respaldo. Luego comenzó eclipse y esperó a que terminaran todos los procesos en segundo plano. Luego cerré eclipse y moví mi copia de seguridad de workbench.xmi hacia atrás (sobrescribiendo la creada con el último lanzamiento). Eclipse se lanzó bien y recuperé todas mis configuraciones.

Si eliminó todos los datos en el directorio .metadata. Existe una forma rápida de importar todos sus proyectos nuevamente. Prueba esto:

Archivo -> Importar -> General: seleccione proyectos existentes en el espacio de trabajo -> Seleccionar directorio raíz: busque la carpeta del espacio de trabajo anterior (la MISMA con la carpeta del espacio de trabajo actual es correcta) -> Finalizar.

Probé varias de las opciones publicadas en este artículo, pero me funcionó al usar esta opción en eclipse.ini:

-Dorg.eclipse.swt.browser.DefaultType = mozilla

Probé la opción anterior de mover los complementos pero no funcionó. Mi solución fue eliminar toda la carpeta .metadata. Esto significó que perdí mis valores predeterminados y tuve que importar mis proyectos nuevamente.

Lea mi respuesta si recientemente ha estado usando una conexión VPN.

Hoy tuve exactamente el mismo problema y aprendí cómo solucionarlo sin eliminar ningún complemento. Así que pensé que tal vez compartiría mi propia experiencia.

Mi problema definitivamente tuvo algo que ver con Spring Framework

Estaba usando una conexión VPN a través de mi conexión a Internet. Una vez que desconecté mi VPN, todo cambió instantáneamente.

Definitivamente una cosa de red / proxy. Me conecto a través de wifi y una puerta de enlace corporativa. Espacio de trabajo eliminado, GGTS reinstalado: aún se bloquea. Apague la red: se inicia bien.

Tengo el mismo problema pero lo resuelvo agregando una variable de entorno (Ejecutar -> Ejecutar configuración -> Variable de entorno) como

variable : java_ipv6
value : -Djava.net.preferIPv4Stack=true
