Here you go.

user.home -> It is user home directory e.i C:\Users\abc (windowdrive:\Users\username) user.dir -> C:\Users\abc\eclipse-workspace\project java.io.tmpdir -> C:\Users\abc\AppData\Local\Temp\ ehcache.disk.store.dir - A system property (https://www.ehcache.org/documentation/3.7/)

For more help feel free to communicate over email [email protected]

I have tried ehcache recently and was wondering what is java.io.tmpdir and where it is located on my machine. The accepted answer in this page didnt solve my issue. I checked /tmp and the ehcache file is not found.

Here's what I find online and hope it helps to other people:

1.run env command on your terminal. It prints the OS environment. In my case, it gave me:

TMPDIR=/var/folders/1j/pb3h7_hl7890px72_f8mntd00000gn/T/

2.alternatively, you can query from python console:

Python 3.5.1 (v3.5.1:37a07cee5969, Dec  5 2015, 21:12:44)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tempfile
>>> tempfile.gettempdir()
'/var/folders/1j/pb3h7_hl7890px72_f8mntd00000gn/T'

It is also possible to utilise a property that will be replaced on compile time. Therefore, you need to configure your pom.xml properly, e.g.

<build>
    <filters>
        <filter>${user.home}/my.properties</filter>
    </filters>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

(at least this was a working setting for our project)

Storage Location are specified by hard coading paths.

Legal values for the path attibute are legal file system paths.

E.g., for Unix: /home/application/cache

The following system properties are also legal, in which case they are translated:

user.home - User's home directory
user.dir - User's current working directory
java.io.tmpdir - Default temp file path
ehcache.disk.store.dir - A system property

Subdirectories can be specified below the system property, for example:

java.io.tmpdir/one

becomes, on a Unix system:

/tmp/one
