I had the same problem on a MacBook Pro i7. Switching editors or views was painfully slow. Solved it by turning off Spring validators that I didn&#39;t need. Go to:

SpringSource Tool Suite -&gt; Preferences -&gt; Spring -&gt; Project Validators

Specifically, I deselected all validators except for Spring Validator, Beans Validator and STS Bean Validator. 



I would also suggest turning off automatic build feature. Uncheck Project -&gt; Build Automatically. Combined with Michael&#39;s suggestions it made difference for me.

Edit: automatic content assist feature was also slowing me down, so I turned it off. I just use it only when I need it by pressing CTRL + Space. See [here][1] for details.

Disable the startup window (called Dashboard) which downloads RSS feeds from the Spring team upon program launch: http://tux2323.blogspot.se/2010/08/eclipse-tipp-reloaded-disable-sts.html. Should you want see it you can use Help-&gt;Dashboard.

Couple of more ways to reduce the memory foot print on Eclipse/STS

1. you can right click on project and choose to close unrelated projects

2. you can try creating working sets with related projects and select only the one  you are working on, you can do this from Top Right corner(View Menu) on the  Project explorer tab

3. Youcan monitor Heapsize, from Preferences General you can check the &quot;Show Heap Status&quot; to show the currently used heapspace , this will show a &quot;recycle bin&quot; icon beside the heap value, you can click this to force Garbage collection



I had a problem with a Maven update process running for a while, every time I launch STS. 

Maven tried to connect to  `http://dist.springsource.com/release/TOOLS/update/e&lt;your_eclipse_version&gt; `

As per [the Jira of STS][1], I changed it to 

`http://download.springsource.com/release/TOOLS/update/e&lt;your_eclipse_version&gt;` 

in &lt;kbd&gt;Window&lt;/kbd&gt; -&gt; &lt;kbd&gt;Preferences&lt;/kbd&gt; -&gt; &lt;kbd&gt;Install/Update&lt;/kbd&gt; -&gt; &lt;kbd&gt;Available software&lt;/kbd&gt;

And now the process is immediate.

I have a set of data that shown below on excel.

    R/V(208,0,32)	YR/V(255,156,0)	        Y/V(255,217,0)
    R/S(184,28,16)	YR/S(216,128,0)	        Y/S(209,171,0)
    R/B(255,88,80)	YR/B(255,168,40)	Y/B(255,216,40)

And I want to separate the data in each cell look like this.

    R/V 208 0 32
    R/S 184 28 16
    R/B 255 88 80

what is the function in excel that I can use for this case.
Thank you in advance.

Besides the following, are there any HTML tag attributes that have a URL as their value?

 * `href` attribute on tags: `&lt;link&gt;`, `&lt;a&gt;`, `&lt;area&gt;`
 * `src` attribute on tags: `&lt;img&gt;`, `&lt;iframe&gt;`, `&lt;frame&gt;`, `&lt;embed&gt;`, `&lt;script&gt;`, `&lt;input&gt;`
 * `action` attribute on tags: `&lt;form&gt;`
 * `data` attribute on tags: `&lt;object&gt;`

Looking for tags in wide usage, including non-standard tags and old browsers as well as HTML 4.01, HTML 5, and XHTML.

I&#39;ve been running STS 2.3.2 on a MacBook Pro for a few days now. I&#39;m finding the performance to be significantly slower than any other build of Eclipse I&#39;ve used. For example, switching from one tab to another can take up to 4 seconds.

I tried turning off much of the validation, and increasing the memory, but it&#39;s not making a difference.

Are others having similar experiences?

Why is SpringSource Tool Suite (STS) so slow? And how can I fix it?

I have a few really long strings in one class for initializing user information. When I compile in Eclipse, I don&#39;t get any errors or warnings, and the resulting .jar runs fine.

Recently, I decided to create an ant build file to use. Whenever I compile the same class with ant, I get the &quot;constant string too long&quot; compile error. I&#39;ve tried a number of ways to set the java compiler executable in ant to make sure that I&#39;m using the exact same version as in Eclipse.

I&#39;d rather figure out how to get the same successful compile I get in Eclipse in Ant than try to rework the code to dynamically concatenate the strings.

Java &quot;constant string too long&quot; compile error. Only happens using Ant, not when using Eclipse

Can anyone point to a functioning [JSLint][1] plug-in for Eclipse?

Is there a working JSLint Eclipse plug-in?

I&#39;m using the PMD plugin for eclipse and it gives me an error when using `System.out.println()` with the explanation:

&gt; System.(out|err).print is used, consider using a logger.

My question is - What is a Logger? How is it used to print to the screen? Why is it better?

Logger vs. System.out.println

I&#39;ve found out that my R.java is never updated, so it doesn&#39;t contain information about my new resources, so I decided to delete it and thought that Eclipse would generate a new one. But that didn&#39;t happen, and I don&#39;t have R.java now. How can I regenerate one?

I&#39;m using Windows&amp;nbsp;7. 

From one of the comments: &quot;Doing *Project* -&gt; *Clean* is what caused the problem for me. Cleaning deletes R.java...and for whatever reason the plugin is not regenerating the file.&quot;


Developing for Android in Eclipse: R.java not regenerating

What is the difference between these things from an Eclipse installation?

* plugins
* features
* dropins folder 

What is the correct use of these folders?


Eclipse plugins vs features vs dropins

There apparently used to be a toggle switch on the Dashboard itself, but that&#39;s gone, and I can&#39;t find anything in the Preferences.  I&#39;m using version 2.5.2.

I know it&#39;s really not a big deal, but closing that window over and over is starting to make Jack a dull boy, if you catch my drift.

Can I disable the Dashboard window when SpringSource Tool Suite starts up?

Maven2: Missing artifact but jars are in place

i got a tricky one:

![look At Breakpoints, they are crossed out!][1]


  [1]: http://i.stack.imgur.com/BxPke.jpg


I can&#39;t set valid breakpoints. Not in Tests, neither in my Java Classes. I searched Stackoverflow and google, but I couldn&#39;t find anybody with the same problem.

I&#39;m using STS(x86) and Maven.

**Edit:** It may seem confusing but I solved it by myself.
I have to go Run-&gt; Skip all Breakpoints (it was set, and I wonder how it was set, because I didn&#39;t do it)

Breakpoints are crossed out, how can I make them valid?

I am starting to configure my development environment and I am using Spring Tool Suite 2.8.1 along with m2E 1.01.

As far as I can tell, since this is a Maven Project (my first), my Maven POM is dictating (along with m2E smarts) my project build configuration and dependencies.

What I would like to know is why my IDE is displaying Java Build Problems that read &quot;Archive required for library *library/path/somejar.jar* cannot be read or is not a valid zip file&quot; when I can see the jars in my .m2 repository?

All the errors pertained to commons-logging:1.1.1 which I excluded in my parent-pom. This was a transistive dependancy via spring-context-support:3.0.5. I excluded that library from my build and now the errors pertain to the spring-context-support library.

I have attached a screenshot to illustrate.
