I\'ve run into problems installing the latest Subclipse plug in. I saw this post: subclipse: Unable to load default SVN Client, but the answer appears to be specific for Sub
I am on Ubuntu and don't have a Mac to validate my answer, but obviously (from your error message) your JavaHL library cannot be found on the java.library.path.
This has nothing to do with the plugin you mentioned (org.tigris.subversion.clientadapter.javahl_1.7.3.jar), don't move that anywhere else. From your link (http://subclipse.tigris.org/wiki/JavaHL#head-5ccce53a67ca6c3965de863ae91e2642eab537de) I assume you tried to install from openCollabNet, which installs the library into /opt/subversion, which is not listed on your java.library.path. You could give it a try and edit eclipse.ini to contain a line like
-Djava.library.path=/opt/subversion
in the -vmargs section; I am not sure if this will solve your problem but it might give you an indication (for example, by getting another error message to proceed with).
I am sorry that I cannot really check my answer, but this hint might help you solving the issue.
I use Eclipse Version: Kepler Service Release 1, Build id: 20130919-0819 on Mac 10.9 and I managed to fix this by installing Subversion using brew:
brew install --universal --java subversion
After running the above command, the installation summary was displayed stating:
svntools have been installed to: /usr/local/opt/subversion/libexec
I went to the /usr/local/opt/subversion/ folder and I searched for the needed jars. I found them in /lib, so in the eclipse.ini file I added:
-Djava.library.path=/usr/local/opt/subversion/lib
I also installed the Subversion plugin from Eclipse using this link:
http://subclipse.tigris.org/update_1.10.x
and it fixed the problem.
I finally gave up using JavaHL and I installed SVNKit 1.6 (make sure to install "SVN Client Adapter" and "SVNKit Adapter" as well) instead.
...And it worked.
Check out this link for solution: http://www.breathedevelopment.com/node/49 It worked for me and it is simple, hope it helps
