简介

Eclipse 4.6.0 Neon无法启动问题，先占个坑。 环境如下： Windows 7 64位, JDK 1.8 之前Mars版本安装运行均无问题。

无法启动

前几天收到邮件，Eclipse 4.6 Neon版本将于2016/06/22执行新的Marketplace策略，所以去下载了eclipse新版本：Neon。

下载安装都很顺利，但是在运行的时候，竟然直接跳出一个错误：

---------------------------

解决方案

参考：http://stackoverflow.com/questions/2493415/unable-to-acquire-application-service-error-while-launching-eclipse

在ecipse.ini或configuration/config.ini中添加org.eclipse.core.runtime 我尝试了一下，发现在eclipse.ini中添加有效。

-Dosgi.bundles=org.eclipse.equinox.simpleconfigurator@1:start,org.eclipse.equinox.common@2:start,org.eclipse.equinox.ds@2:start,org.eclipse.equinox.event@2:start,org.eclipse.update.configurator@3:start,org.eclipse.core.runtime@start

如此，eclipse终于可以成功运行了。

无法创建workspace

运行eclipse之后，首次创建workspace，没想到又一个错误：

尝试了许多办法，仍然还是个这错误。

已向eclipse提问求助。期待他们能够尽量回复给出解决方案

解决方案

原来是eclipse installer的bug，需下载新版本再安装。

{% blockquote Eclipse https://www.eclipse.org/forums/index.php/m/1734197/#msg_1734197 Forums %} Sorry, there was a bug in the RC3 installer. I've just created an RC3a build to fix it. Until they update the link on the website

https://bugs.eclipse.org/bugs/show_bug.cgi?id=495523

you could get the fixed version from here:

https://hudson.eclipse.org/oomph/job/integration/lastSuccessfulBuild/artifact/products/

Or you could switch to Advance mode and use the button at the bottom of the wizard to update your installer to the fixed version. {% endblockquote %}

配置启动问题汇总

{% blockquote EclipseWiki https://wiki.eclipse.org/Eclipse4/RCP/FAQ#Why_won.27t_my_application_start.3F %}

Problems on Configuration, Start-Up, and Shutdown

Why won't my application start?

E4AP products require having the following plugins:

org.eclipse.equinox.ds (must be started) org.eclipse.equinox.event (must be started) Note that org.eclipse.equinox.ds and org.eclipse.equinox.event must be explicitly started. In your product file, you should have a section like the following:

  <configurations>
     <plugin id="org.eclipse.core.runtime" autoStart="true" startLevel="2" />
     <plugin id="org.eclipse.equinox.ds" autoStart="true" startLevel="3" />
     <plugin id="org.eclipse.equinox.event" autoStart="true" startLevel="3" />
  </configurations>

Failure to set the auto-start levels usually manifest as runtime errors like

  Unable to acquire application service. Ensure that the org.eclipse.core.runtime bundle is resolved and started (see config.ini)
