Eclipse在加载工作台时挂起

Question

我的eclipse停止加载工作台。我已经尝试过从./eclipse --clean开始

当从控制台启动时，会抛出以下异常：

java.lang.NullPointerException

加载com.android.ide.eclipse.adt时停止

我的工作台怎么了？

Answer 1

DISCLAIMER: THIS WILL DELETE ALL OF YOUR ECLIPSE WORKSPACE SETTINGS AND YOU WILL HAVE TO RE-IMPORT ALL YOUR PROJECTS, THERE ARE LESS DESTRUCTIVE ANSWERS HERE

尝试以下操作：

1. 删除本地工作区中的.metadata文件夹(我就是这么做的)。它似乎包含一个.LOCK文件，如果没有正确关闭，就会阻止eclipse正常启动。在基于Unix的系统中，您可以在命令行中键入以下内容；

rm -r workspace/.metadata

• Delete您的主目录中的.eclipse目录。启动eclipse。如果这不起作用，

• 将在另一个用户帐户下打开eclipse。如果它加载，您就知道问题出在您的帐户上，而不是您的eclipse installation.

。

Answer 2

在http://off-topic.biz/en/eclipse-hangs-at-startup-showing-only-the-splash-screen/上展示的过程对我很有效：

.metadata/.plugins

• mv org.eclipse.core.resources.bak

• Start

1. cd org.eclipse.core.resources eclipse。(它应该显示一条错误消息或一个空工作区，因为找不到任何项目。)
2. 关闭所有打开的编辑器选项卡。
3. 退出eclipse。
4. rm -rf org.eclipse.core.resources (删除新创建的eclipse.eclipse.core.resources.bak/ org.eclipse.core.resources (恢复原始eclipse并开始工作。:-)

在其他答案中：

eclipse -clean -clearPersistedState

这似乎有相同甚至更好的效果。

这是一个用于MacOS (使用Macports)和Linux (使用eclipse Equinox在Ubuntu上测试)的脚本，它可以通过一个可选的终止正在运行的Eclipse来开始。您可能希望调整脚本以满足您的需要。如果您添加了新平台，请编辑此答案中的脚本。

#!/bin/bash
# WF 2014-03-14
#
# ceclipse:
#   start Eclipse cleanly
#
#   this script calls eclipse with -clean and -clearPersistedState
#   if an instance of eclipse is already running the user is asked
#   if it should be killed first and if answered yes the process will be killed
#
# usage: ceclipse
#

#
# error
#
#   show an error message and exit
#
#   params:
#     1: l_msg - the message to display
error() {
  local l_msg="$1"
  echo "error: $l_msg" 1>&2
  exit 1

Answer 3

./eclipse -clean -refresh

正如sulai Dec 20 '12在12:46的评论中提到的，这对我很有效。

然而，在Mac上，我必须弄清楚如何访问./eclipse

以下是解决方案：

cd Eclipse.app/Contents/MacOS/
