The solution to install the SVN plugin javaHL not available under Mac

background:

The reason for installing this is to use svn gap svnkit before

This error is reported when merging the code.

text:

After installing the Eclipse plug-in svnEclipse plug-in under Mac, the following pop-up box will pop up every time you open Eclipse:

You are prompted that the JavaHL Library is missing from your machine.

Select Eclipse→Preferences→Team→SVN, and you can see that the definition of the SVN interface Client is as follows:

technology sharing

This shows that JavaHL is missing in the current system and needs to be installed manually.

The introduction given on the subeclipse official website (http://subclipse.tigris.org/wiki/JavaHL may be very slow to open) says that there are two ways to install the JavaHL Library on a Mac computer (OS X), one is through MacPort , one is in the form of HomeBrew. as the picture shows:

Here we mainly introduce the use of HomeBrew to implement the installation.

Step 1: Install HomeBrew:

The installation of HomeBrew depends on XCode and Commond Line. The specific installation steps are as follows:

1. Install Xcode

2. Install the command line tools, open the terminal, and enter the command:

xcode-select - - install so that the system after mac 10.9 will install command line tools

3. Install brew, open the terminal, and enter the command:

curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1

4. Update brew, open the terminal, and enter the command: (ignorable)

brew update

5. Diagnose the system, open the terminal, and enter the command: (ignorable)

brew doctor

HomeBrew的安装过程介绍网上也有很多教程，比如：

就不更多介绍了，如果安装过程遇到了问题，百度下基本都能解决的。

步骤2：执行命令，安装JavaHL

进入终端，键入如下命令：

brew install --universal --java subversion

但是会遇到如下问题，提示有个包下不到，原因你懂得，被墙了。

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

==> 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
==> Summary
??  /usr/local/Cellar/subversion/1.8.13: 119 files, 18M, built in 11.3 minutes

整个安装过程会持续很长时间，千万不要中途关掉终端。

步骤2.4：执行命令绑定Java环境和Java延伸目录的关系：

正如上面安装过程最后提示的那样：

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

依次在终端中执行上面两句命令，整个安装过程就完成了。

安装后，在进入Eclipse查看SVN Client的配置如下：

问题解决~！

纵观整个安装过程，简要来说分为如下过程：

1：安装Brew；

2：下载包，改名，放在指定目录下；

3: Execute the installation command and its supplementary commands;

Most of the posts on the Internet that introduce the solution to JavaHL not available only introduce the first and third parts, but the second part is missing. I don't know if they are all installed by FQ or installed abroad, so they have not encountered a wall. Caused the problem that the corresponding file could not be downloaded. Step 2 is now added, hoping to help you solve this problem.
