一、修改eclipse.ini：

    将本地的eclispe直接拷贝到另一台机器上，运行eclipse.exe直接抛出错误：

The Eclipse executable launcher was unable to locate its companion shared library

    这是由于eclipse.ini中的 --launcher.library 配置有问题，编辑eclipse.ini文件：

--launcher.library
C:/Users/zhouy/.p2/pool/plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.700.v20180518-1200

    可以看到这里的用到了.p2里的内容，故将我本地的.p2文件夹打包发过去，并且将其中的用户改为新电脑上的当前登录用户。所有这些准备好之后再次运行eclipse.exe结果再次跑出了错误，错误如下：

二、修改config.ini

    错误提示如下：

java.lang.IllegalStateException: Unable to acquire application service. Ensure that the org.eclipse.core.runtime bundle is resolved and started (see config.ini).
	at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:74)

	at org.eclipse.equinox.launcher.Main.run(Main.java:1311)

    查找资料发现是由于config.ini文件的问题，文件内容如下：

#This configuration file was written by: org.eclipse.equinox.internal.frameworkadmin.equinox.EquinoxFwConfigFileParser

osgi.bundles.defaultStartLevel=4
eclipse.application=org.eclipse.ui.ide.workbench
eclipse.p2.data.area=file\:/C\:/Users/zhouy/.p2/

    可以看到这个文件也用到了.p2里的东西，所以将用户改为新电脑上的用户即可，在这个用户文件夹下肯定是找不到.p2文件夹及内容的。

    改好之后错误依旧，仔细查看信息发现下面这条信息和报错信息很相似。所以做如下修改：

三、修改bundles.info

    bundles.info部分内容如下：

#encoding=UTF-8
#version=1
bcpkix,1.59.0,file:/C:/Users/zhouy/.p2/pool/plugins/bcpkix_1.59.0.jar,4,false
bcprov,1.59.0,file:/C:/Users/zhouy/.p2/pool/plugins/bcprov_1.59.0.jar,4,false

    可以看到文件中出现了很多地方用到了.p2目录，故将用户批量替换为新电脑上的用户然后保存。

    再次运行eclipse.exe即可正常打开。
