在Mac下安装Eclipse插件svnEclipse插件后，每次打开Eclipse都会弹出如下弹出框：

提示你本机缺少JavaHL Library。
选择Eclipse→偏好设置（preference）→Team→SVN，可以看到SVN接口Client的定义如下：

这说明当前系统中缺少JavaHL，需要我们手动安装。
subeclipse官网（http://subclipse.tigris.org/wiki/JavaHL 打开可能会非常慢）给出的介绍说有两种方式可以在Mac电脑上（OS X）上安装JavaHL Library，一种是通过MacPort，一种是通过HomeBrew的形式。如图所示：



==> Downloading https://www.apache.org/dyn/closer.cgi?path=subversion/subversion
Already downloaded: /Library/Caches/Homebrew/subversion-1.8.13.tar.bz2
==> Patching
patching file configure
Hunk #1 succeeded at 25386 (offset 20 lines).
patching file subversion/bindings/swig/perl/native/Makefile.PL.in
==> Downloading https://serf.googlecode.com/svn/src_releases/serf-1.3.8.tar.bz2
curl: (7) Failed to connect to serf.googlecode.com port 443: Operation timed out
Error: Failed to download resource "subversion--serf"
Download failed: https://serf.googlecode.com/svn/src_releases/serf-1.3.8.tar.bz2




这个问题也有解决的办法，那就是下载对应的包，放在对应的目录下，这样就能再安装JavaHL的过程中跳过serf-1.3.8.tar.bz2的下载了。
步骤2.1：下载serf-1.3.8.tar.bz2包：
http://download.csdn.net/detail/shanwenchao/8653245
下载后放在任意目录，将名称修改为：subversion--serf-1.3.7.tar.bz2
 
步骤2.2：将改名后的该文件放在目录下：
将修改后的文件放在/Library/Caches/Homebrew目录下。
 
步骤2.3：重新执行安装命令，安装JavaHL:

brew install --universal --java subversion


这是就不会下载而是直接从文件目录中取该包了。如下过程：


brew install --universal --java subversion
Warning: subversion: --java was deprecated; using --with-java instead!

==> Caveats
svntools have been installed to:
/usr/local/opt/subversion/libexec
You may need to link the Java bindings into the Java Extensions folder:
sudo mkdir -p /Library/Java/Extensions
sudo ln -s /usr/local/lib/libsvnjavahl-1.dylib /Library/Java/Extensions/libsvnjavahl-1.dylib
Bash completion has been installed to:
/usr/local/etc/bash_completion.d
