无法启动 Eclipse - Java 已启动但返回退出代码 = 13

Question

I am trying to get my first taste of Android development using Eclipse. I ran into this problem when trying to run Eclipse, having installed version 4.2 only minutes ago.

After first trying to start Eclipse without any parameters to specify the Java VM, I got an error message saying it couldn't find a Java VM called javaw.exe inside the Eclipse folder , so I found where Java was installed and specified that location as the parameter in the shortcut's target. Now I get a different error, Java was started but returned exit code=13 .

Similar questions seem to indicate that it's a 32-bit/64-bit conflict, but I'm 99% positive that I downloaded 64-bit versions of both Eclipse and Java (RE 7u5) , which I chose because I have 64-bit Windows 7.

• If anyone knows how to confirm that my Eclipse and Java are 64-bit, that'd be appreciated.
• If you think my problem is a different one, please help!
• Please speak as plainly as you can, as I am totally new to Eclipse and Java.

Shortcut Target: "C:\\Program Files\\Eclipse-SDK-4.2-win32-x86_64\\eclipse\\eclipse.exe" -vm "C:\\Program Files (x86)\\Java\\jre7\\bin\\javaw.exe"

Answer 1

Your version of Eclipse is 64-bit, based on the paths and filenames. However, the version of Java that it's picking up is 32-bit, as indicated by where it is coming from, on this line:

-vm C:\Program Files (x86)\Java\jre7\bin\javaw.exe

Program Files (x86) is the folder where 64-bit Windows places 32-bit programs.

Program Files is the folder where 64-bit Windows places 64-bit programs.

This can happen when a system has more than one JVM installed, as is often the case on Windows 64-bit (for example, the JRE download page uses the bit-ness of the browser to determine what bit-ness download to offer you, and many people use(d) 32-bit browsers even though they run 64-bit Windows).

The best way to fix this, assuming you do in fact have 64-bit JRE or JDK on your system, is to specify in eclipse.ini exactly which JVM you want it to use. The instructions are detailed in the Eclipse wiki page , but basically you have to specify the -vm option in the ini file - make sure to read the wiki page carefully as the format is very specific.

Specifying the JVM path in eclipse.ini is strongly recommended because doing so isolates Eclipse from any potential changes to your system PATH that some program installers might make (I'm talking to you, Oracle!).

Another option would be to download and use 32-bit Eclipse instead of 64-bit, but it's still strongly recommended to specify the path to the JVM in eclipse.ini .

Left for historical reference :

To check your version of Java, run

java -version

in a console (command prompt). On Windows 7 with 64-bit Java 6 I get:

java version "1.6.0_27"
  Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
  Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)

Note the 3rd line, which shows that this is a 64-bit version.

On a 32-bit version you'll get something like:

Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)

If you are on a 64-bit machine, then you can install the 64-bit JDK and uninstall the 32-bit one. For instance on Windows 10, just go to Settings and under Apps, you will find Java. Click on it and you will find all the different versions. Now you can select which one to uninstall.

Answer 2

I got this error and found that my PATH variable (on Windows) was probably changed. First in my PATH was this entry:

C:\ProgramData\Oracle\Java\javapath

...and Eclipse ran "C:\\ProgramData\\Oracle\\Java\\javapath\\javaw" - which gave the error. I suspect that this is something that came along with an installation of Java 8.

I have several Java versions installed (6,7 and 8), so I removed that entry from the PATH and tried to restart Eclipse again, which worked fine.

If it's doesn't work for you, you'll need to upgrade your JDK (to the Java versions - 8 in this case).

Answer 3

There are working combinations of OS, JDK and Eclipse bitness. In my case, I was using a 64-bit JDK with a 32-bit Eclipse on a 64-bit OS. After downgrading the JDK to 32-bit, Eclipse started working.

Use one of the following combinations.

• 32-bit OS, 32-bit JDK, 32-bit Eclipse (32-bit only)
• 64-bit OS, 32-bit JDK, 32-bit Eclipse
• 64-bit OS, 64-bit JDK, 64-bit Eclipse (64-bit only)

Answer 4

如果您最近安装了 Java 8 并卸载了 Java 7，请安装 JDK 8 并重试。

Answer 5

For me the solution was to go into (on Windows 8.1):

System > Advanced system setting > Environment Variables 

Under 'System variables' in the 'Path' variable there was the following first:

C:\ProgramData\Oracle\Java\javapath;

I removed this and Eclipse worked again!

Answer 6

I had the same issue, Java was started but returned exit code=13 .

My solution was to create an environment variable to Windows properties variable name = PATH variable value = C:\\Program Files\\Java\\jdk1.7.0_02\\bin , not to C:\\Program Files (x86)\\Java\\jre7\\bin .

Next I added a line to file eclipse.ini → C:\\Program Files\\Java\\jdk1.7.0_02\\bin\\javaw.exe.

That worked for me.

Answer 7

The issue was fixed by doing the following steps.

1. Eclipse finds the JAVA executables from 'C:\\ProgramData\\Oracle\\Java\\javapath'

2. The folder structure will contain shortcuts to the below executables,
   i. java.exe
   ii. javaw.exe
   iii. javaws.exe

3. For me the executable paths were pointing to my Program Files(x86) (home for 32 bit applications) folder location

4. I corrected it to Program Files (which homes 64-bit applications) and the issue got resolved

Please find the screenshot for the same.

Answer 8

Adding vm argument to .ini file worked for me

-vm
C:\Program Files\Java\jdk1.7.0_65\bin\javaw.exe

Answer 9

The strangest fix ever. Look at your Eclipse path, and make sure you do not have strange characters (like ! , # , and @ ). It worked for me.

Answer 10

Locate eclipse.ini:

Often at C:\\Users\\xxx\\eclipse\\jee-neon\\eclipse , add

-vm
 C:\Program Files (x86)\Java\jre7\bin\javaw.exe

after

--launcher.appendVmargs

Answer 11

我卸载了 Java 更新 25，问题解决了。

Answer 12

A clean reinstall of the Java JDK did the trick in my case. I am running Eclipse 4.4 (Luna) like a charm now.

Answer 13

You have to go to the folder where eclipse is installed and then you have to change the eclipse.ini file.

You have to add

-vm

C:\\Program Files\\Java\\jdk1.8.0_202\\bin\\javaw.exe

Your eclipse.ini file will look like the below screenshot

Answer 14

The solution is simple: Put the "eclipse" folder on "C:/Program Files". If it does not work, put it in "C:/Program Files (x86)".

Answer 15

It turned out I only had the 32-bit Java runtime installed.

C:\Program Files (x86)\Java\jre1.8.0_45\

All Eclipse really wanted was for me to install the 64-bit Java runtime. <= SOLVED

Java SE Runtime Environment 8u45  jdk-8u45-windows-x64.exe

http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

Confirm your installation by checking you now have this folder

    C:\Program Files\Java\jre1.8.0_45\

Answer 16

The best answer here is too long. I cannot comment so I added my answer.

1. Go here: http://www.oracle.com/technetwork/java/javase/downloads/index.html
2. Download the latest SDK (of course for x64 if your computer is x64)
3. Install it
4. Now the party is finished, and it's time to work with Eclipse ;)

Answer 17

当我忘记安装 JDK 时，我收到了这条消息。

Answer 18

I had the same problem. I was using Windows 8 with a 64-bit OS. I just changed the path to Program Files (x86) and then it started work. I put this line in the eclipse.ini file:

-vm
 C:\Program Files (x86)\Java\jre7\bin\javaw.exe

Answer 19

确保 Eclipse 路径中没有特殊字符（ % 、 $ 、 #等）。

Answer 20

If you install a 64-bit Eclipse version on a PC with a 32-bit JRE this is guaranteed to occur.

So the solution is quite straightforward: You need to synchronise them by updating either one. This shall happen when downloading Oracle Fusion middleware and Eclipse expects a 32-bit environment while your JRE is 64-bit and your JAVA home is pointing to a 64-bit JDK.

Answer 21

1. Under system environment variables, make sure "C:\\ProgramData\\Oracle\\Java\\javapath" is removed.

2. Under system environment variables, make sure "C:\\Program Files\\Java\\jdk1.8.0_131\\bin" is added.

Answer 22

I tried some of the solutions, but not worked for me.

Finally, I found another way, ...

Go to Environment Variables → System Variables

Set C:\\Program Files\\Java\\jdk1.7.0_02\\bin\\javaw.exe to the path in the system variables.

Try it. It worked for me...

Answer 23

I tried the following solution:

I created a shortcut of javaw.exe from path C:\\Program Files\\Java\\jdk1.7.0_71\\bin and pasted it into the path C:\\ProgramData\\Oracle\\Java\\javapath .

After that, I launched Eclipse, and it worked for me.

Answer 24

I had this issue. I installed Java 8 update 25 via Chrome, and therafter attempting to start Eclipse gave the mentioned error.

Uninstalled that update, and Eclipse works again.

Answer 25

I also encountered the same issue. It turned out that the environment variable Path was pointing to an incorrect Java version.

Please check the environment variable and point it to the correct Java. For example:

C:\Program Files (x86)\Java\jdk1.6.0_17\bin

To check the environment variable, go to:

Computer → properties → Advanced system settings → Advanced -> Environment variables

Answer 26

It could be due to too little memory. You can modify the eclipse.ini file to increase the memory. Something like this might help you: FAQ How do I increase the heap size available to Eclipse?

Answer 27

I have just solved the same issue upon setting up my Windows 8.1 PC. Exactly like @George Papatheodorou mentioned above (sorry I cannot add a comment), Eclipse and JRE must be both 64 bit or 32 bit.

However, it seems for Windows 8/8.1 environment, you are going to get 32-bit JRE by default (and I do not know where to change that default for the download), as explained here: http://java.com/en/download/faq/win8_faq.xml

I was using 64-bit Eclipse so there was a discrepancy. I then installed 32-bit Eclipse and everything works fine this time.

So before bothering changing any environment variables, check your JRE and Eclipse version.

Of course you can use 64-bit JRE with 64-bit Eclipse. Just make sure they match because Windows 8.1 will give you 32-bit by default.

Answer 28

I had a similar error after installing Java 8 on my Windows 7 system, 64 bit system.

Changing environment variables, etc. did not help. So I tried to remove the Java Update 8, but that too did not help. Downloading and installing the 64-bit version of Java 8 SDK fixed my problem. I hope this helps.

Answer 29

I had the same issue after I upgraded my JDK from 1.7 to 1.8. I'm using Eclipse 4.4 (Luna). The error is gone after I degrade JDK to 1.7.

Answer 30

Please check whether you have set two JAVA paths in the Environment Variable section. If you already installed two versions of the JDK, it might be, then double check you have put PATH for Java like below.

PATH -->  C:\ProgramData\Oracle\Java\javapath

and also

JAVA_HOME ---> C:\Program Files\Java\jdk1.7.0_02\bin

If both are there, then this sort of error may occur.

If it's OK, then check in the ".ini" file the below area is OK or not. Open ".ini" file and check

 -VM  path is  C:\Program Files\Java\jdk1.7.0_79\bin\

If not, please set it like that and run again.
