Answer 1

Answer on the behalf of OP:

This version is missing tools.jar: jdk-8-ea-bin-b106-windows-i586-05_sep_2013.exe

It is now in the most recent release.

Answer 2

I was using Hadoop-Common-2.7.2 as a dependency, When I add exclusions in my POM.xml, my issue got resolved.

<dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-common</artifactId>
        <version>2.7.2</version>
        <exclusions>
                <exclusion>
                <groupId>jdk.tools</groupId>
                <artifactId>jdk.tools</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Answer 3

When I looked at Eclipse > Window > preference > Java > Installed JRE > it was pointing to JRE, which seems obvious, but when I changed the pointing to JDK the compile error was resolved since there was tools.jar now in JDK.

Before this I had tried copying tools.jar from jdk/lib to jre/lib, but that did not solve the issue.

Answer 4

The error only appears when I hadn't installed the JDK in its default directory.

Install it on the default directory to resolve the problem.

Answer 5

tools.jar was removed in Java 9. https://docs.oracle.com/javase/9/migrate/toc.htm#GUID-12237744-E23B-42F8-8892-26BA1BDD63F2

Answer 6

The solution is to update the eclpise.ini, If no JDK is used for Eclipse, change it:

• Quit Eclipse if it is running
• Go to the Eclipse installation directory and open the file eclipse.ini in a text editor.
• Search for the line -vmargs
• Before the line -vmargs, add two lines:
• On the first line, write -vm
• On the second line, write the path to your JDK installation (usually something like: C:\Program Files\Java\jdk1.6.0_31\bin\javaw.exe on Windows)*
