When I tried to run a plug-in project as Eclipse Application, I get following error.

Then, I found out that the folder "/{HOME}/.swt/lib/macosx/x86_64" acctually is empty. I guess this is the reason, but I do not know how to reinstall SWT(I have googled a while though)

JUnit Plug-in Test Ignores Target Platform in Eclipse Neon

I have some problems getting JUnit plug-in tests to work using Eclipse Neon M7 and I'd really like input from anybody out there who uses tests (there has to be somebody, right?).
Whenever I start a test that works in Eclipse Luna (but didn't in Mars, which I assumed was a bug) and continues to work using Tycho I get the following exception:

Clearly it's not a Eclipse bug at this point, but I'm doing something wrong. There is no indication what kind of plug-ins are started in the test, but judging from the version ranges I assume it's the wrong ones again - the plug-ins of the running Eclipse instance instead of the plug-ins defined in the workspace's target platform.
Still the launch configuration claims the later target platform is used.
How do I configure a plug-in unit test so that it will take the currently active target platform?

The problem here is that Eclipse 4.4 (Luna, 2014) and below had a version of org.eclipse.core.runtime that was compatible with the host Eclipse version of org.eclipse.pde.junit.runtime. That changed with 4.5 when the dependency increased.
As you have correctly concluded that the configuration is pointing at the wrong org.eclipse.pde.junit.runtime. This is probably due to uncleared configuration state. Ensure that the configuration is being cleared, so you don't run with a stale version. That is ensure that Clear the configuration area before launching is checked in the Configuration tab of launch configuration.
You can see exactly what PDE has resolved as the configured bundles by looking at ${workspace_loc}/.metadata/.plugins/org.eclipse.pde.core/pde-junit/org.eclipse.equinox.simpleconfigurator/bundles.info (location specified in Configuration tab of launch configuration)

Eclipse Kepler crashes in a certain workspace

I have a Dropbox workspace, and recently(this has never happened before), I came home(I edited some code at school also in the Dropbox workspace), and now Eclipse crashes everytime I use that workspace, but not any of my other workspaces. I have reinstalled Eclipse and tried to allocate from 512mb to 2gigs of RAM but nothing has happened. I've trimmed down the error code b/c it's over 52,000 characters long.

Please try the following:
Try deleting the file .metadata/.plugins/org.eclipse.core.resources/.snap or any .snap file under .metadata/.plugins/org.eclipse.core.resource.
You can do that using:
$ cd eclipse-workspace/.metadata/.plugins/org.eclipse.core.resources
$ find . -type f -name "*.snap" | xargs rm
Delete the .metadata directory from your workspace and restart
Ensure that your workspace and projects have all the necessary permissions, try 777 for now.

Try these steps.
If you are using debian based os, use
sudo apt-get install eclipse-platform
It's maintained. Else download the IDE for linux from here.
Install OpenJDK not oracle java 7.
sudo apt-get install openjdk-7-jdk
If you need to use oracle jdk, see this article. It's working for me in Ubuntu 12.10

Try this:
ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/
