  • Using IDE built-in plugin system:

    • Preferences > Plugins > Browse repositories... > Search for "Env File" > Install Plugin
  • Manually:

    • Download the latest release and install it manually using Preferences > Plugins > Install plugin from disk...

Restart IDE.


  1. Add new Run/Debug configuration: + Add new configuration > ...
  2. Switch to EnvFile tab
  3. Select Enable EnvFile checkbox
  4. Select Substitute Environment Variables checkbox (if needed)
  5. Select Process JetBrains path macro references checkbox (if needed)
  6. Select Ignore missing files checkbox (if needed)
  7. Select Enable experimental integrations checkbox (if needed)
  8. Click on + to add a file
  9. Adjust order as needed
  10. Even variables defined within run configuration can be processed, ordered and substituted

Read from file


Hidden files

Hidden files (starting with a dot) are not displayed in Finder on macOS by default. To toggle hidden files in the Open dialog, press COMMAND + SHIFT + .. Alternatively, one can either tweak macOS to show hidden files or select any file using standard Finder dialog and then manually edit path by double-clicking on the entry in the table.

Experimental Integrations

Not all run configurations available in IDEA-based IDEs are implemented similarly. Some of them differ significantly. In certain cases (so far, only Gradle has been confirmed) the implementation exposes interfaces to integrate the EnvFile UI but doesn't provide interfaces for it to actually make its work. Luckily, it was possible to make few assumptions about IDEA's internal implementation and make it work. Such integration is very fragile and it's not immediately clear if it will affect any existing integrations and when it will break. For that reason there is a special option to Enable Experimental Integrations that can be enabled when desired and should prevent other integrations from breaking.



# This line is ignored since it's a comment


# This line is ignored since it's a comment
SECRET_KEY hip-hip-env-files


    # JSON doesn't have comments but since JSON is subset of YAML
    # We parse it with YAML parser and therefore have comments
    # And even trialling commas in objects :)
    "SECRET_KEY": "hip-hip-env-files",
    "VERSION": "1.0", # All non-string literals should be enclosed in quotes; btw this is ignored too


# This line is ignored since it's a comment
SECRET_KEY: hip-hip-env-files
VERSION: "1.0" # All non-string literals should be enclosed in quotes; btw this is ignored too

Bash (workaround)

There was a number of requests to support extracting environment variables from bash scripts like:

export SECRET_KEY="hip-hip-env-files"
export VERSION="1.0"

The feasible way to do that is yet to be discovered (if any at all) so the plugin does not support that at the moment. On the other hand there is a simple workaround that can be used for the time being. The example bash script from above can be split into an .env file and a generic script that can be used to set environment variables on a command line:




while read -r line; do export $line; done < .env


$ . set-env.sh
$ echo $VERSION

Variable Expansion

EnvFile also supports environment variable substitution. It's optional and disabled by default. Implementation is based on StringSubstitutor so it's the best reference for how it works.


Syntax is derived from Bash but is way more primitive:

A=${FOO}            # A=""        <- unknown variables replaced by empty strings
B=${FOO:-default}   # B="default" <- default values can be set as in Bash
C=${B}              # C="default" <- it's possible to refer to other variables that were previously evaluated
D=$${C}             # D="$${C}"   <- double dollar serves as an escape character
E=$C                $ E="$C"      <- curly brackets are required


Environment variables are evaluated in the order they are defined in files. Files are evaluated in the order defined in EnvFile UI. Environment variables defined in run configuration can be ordered relatively to files. Order between environment variables defined in run configuration is not defined.

It is possible to refer to any environment variables that were evaluated previously - within same file or from other sources.

Path Macro Substitution

EnvFile can substitute JetBrains path macro references such as $PROJECT_DIR$ etc. It's optional and disabled by default. For details - see "Working with $PROJECT_DIR$ in plugin configuration options".

Further Development

  • Add more formats (upon requests)
  • Add support for other JetBrains products/plugins (upon requests)
  • Add more tests (¯\_(ツ)_/¯)


EnvFile uses Gradle for building.

$ ./gradlew clean test build
  59 actionable tasks: 59 executed
$ ls -1 build/distributions
  Env File-2.1.1-SNAPSHOT.zip

In order to open plugin's project in IDE, just open it as a Gradle project. Then use intelij:runId on the root of the project to launch an IDEA instance. You can set IDE env var for the run configuration pointing at IDE folder (IDE Folder/Content on macOS) to test plugin with different versions.
