首先要确定subclipse的版本，当前最新版本是1.10.x，需要对应的subversion是1.8.x，对应关系见：http://subclipse.tigris.org/wiki/JavaHL#head-5ccce53a67ca6c3965de863ae91e2642eab537de
目前Ubuntu 13.04应用中心的subversion是：subversion 1.7.5-1ubuntu3.1，所以1.10.x版本的subclipse是不能装的。
安装subclipse1.8.x，eclipse->install new software-->add subclipse1.8.x地址，pending以后，把子项都选上，安装。
重启eclipse以后，出现寻找JAVAHL错误，error信息：
Failed to load JavaHL Library.
These are the errors that were encountered:
no libsvnjavahl-1 in java.library.path
no svnjavahl-1 in java.library.path
no svnjavahl in java.library.path
java.library.path = /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
解决办法
If you do not need to use JavaHL, Subclipse also provides a pure-Java SVN API library -- SVNKit (http://svnkit.com). Just install the SVNKit client adapter and library plugins from the Subclipse update site and then choose it in the preferences under Team > SVN.
Go to Eclipse > Preferences > Team > SVN Under "SVN interface", choose client as "SVNKit(Pure Java) SVNKit v..xx". Worked for me.
我这样就可以了，如果还不行，试试把Eclipse重启动。
