Error Installing Eclim, "SKProfile" is not a valid indentifier

I am trying to get Eclim installed on my Debian Windows Subsystem For Linux (WSL) virtual machine under Windows 10. It appears that my issues have to do with the SDK in some way, but I'm unsure of how to fix this. Any help would be greatly appreciated. Below is my log file containing the stacktrace.

Try installing latest, Eclipse 4.8.x (Photon), which is one of the requirements in the installation instruction. That fixed it for me.

What happened?

The version of Eclipse you are trying to use (probaby 3.8 or 4.2 judging by the plugin ids) is very old and doesn't understand Java 9. The layout of the Java 9 JRE/JDK directories has changed significantly and this is confusing this old Eclipse.
Use Eclipse Oxygen.2 4.7.2 to run with Java 9 or use Java 8 to run the old version of Eclipse.

In Eclipse IDE it can run, but when I export it I got an error.
Someone that can help me with this?

The org.eclipse.equinox.launcher plug-in is missing from the build (or possibly it is present but has the wrong version).
The configuration of plug-ins included in the RCP is separate from the configuration for the plug-ins used when you test your RCP from within Eclipse.
If you are using a '.product' file for the RCP go to the 'Contents' tab in the .product file editor and click the 'Add Required' button to add all the required plugins to the product. For a normal RCP there should be something like 100+ plugins in the contents list. Then rebuild the RCP.
In the above I am assuming you are using a 'plug-ins based' product configuration.

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 Juno doesn't start - An error has occurred. See the log file [\.metadata\.log.]

I am using Eclipse Juno on windows 7 machine.
Solution I tried -
Created new workspace and tried - not working
Deleting .metadata folder fro exiting workspace - not working
eclipse/dir> eclipse -clean - not working
Re installation of JDK - not working
P.S. -
I didn't have any .snap files

Try re_installin Java Runtime Environment(JRE). If the problem keeps, you must change or replace your internal libraries of JAVA.

I was getting the same issue. I tried with different version of Eclipse and everything is fine now (to be specific I tried lower version).
I am sorry if it is not working for you or you want this particular version only but this is how I started working back after getting stuck.
