eclipse使用

自动补全

首次使用eclipse，发现没有代码提示，怎么可能？？？

解决办法如下:

In case someone comes here and want to activate the autocomplete function, go to

Preferences -> Java -> Editor -> Content Assist.

Then in the Auto Activation section fill in Auto activation triggers for Java:

abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._

安装FatJar

我的eclipse版本是MAC版4.7.0，直接安装FatJar，发现装不上去。这时候需要安装低版本eclipse框架:

通过Help -> Install New Software… -> Work with.
选择"The Eclipse Project Updates - http://download.eclipse.org/eclipse/updates/4.7"
然后 勾选”Eclipse Tests, Examples, and Extras” 下的 “Eclipse 2.0 Style Plugin Support”

我比较悲催，之后安装FatJar又报错了:

An error occurred during the org.eclipse.equinox.internal.p2.engine.phases.CheckTrust phase.

session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.CheckTrust, operand=, action=).

Error reading signed content.

Exception in opening zip file: /Applications/Eclipse.app/Contents/Eclipse/plugins/net.sf.fjep.fatjar_0.0.31

 

解决方法是:删除eclipse根目录中的artifacts.xml文件，重启eclipse，再次安装FatJar。
