How to configure “Shorten command line” method for whole project in IntelliJ

问题

When I run tests I get the error "Command line is too long". It works if I set the "Shorten command line" method in the Run/Debug configuration to "JAR manifest" for the specific method or class, but how do I set it for the whole project or is there an IDE global setting for it?

回答1:

You can set up a default way to shorten the command line and use it as a template for further configurations by changing the default JUnit Run/Debug Configuration template. Then all new Run/Debug configuration you create in project will use the same option.

Here is the related blog post about configurable command line shortener option.

Inside your .idea folder, change workspace.xml file

Add

<property name="dynamic.classpath" value="true" />

  <component name="PropertiesComponent">
.
.
.
  </component>

Example

 <component name="PropertiesComponent">
    <property name="project.structure.last.edited" value="Project" />
    <property name="project.structure.proportion" value="0.0" />
    <property name="project.structure.side.proportion" value="0.0" />
    <property name="settings.editor.selected.configurable" value="preferences.pluginManager" />
    <property name="dynamic.classpath" value="true" />
  </component>

If you don't see one, feel free to add it yourself

 <component name="PropertiesComponent">
    <property name="dynamic.classpath" value="true" />
  </component>

Intellij 2018.2.5

Run => Edit Configurations => Choose Node on the left hand side => expand Environment => Shorten Command line options => choose Classpath file or JAR manifest

This works for me

You also can do this

1) In file workspace.xml you can find

<component name="ProjectManager">
    <defaultProject>
        <component name="RunManager"> ...some configurations... </component>

2) And add to "some configurations" two default configurations

<configuration default="true" type="JUnit" factoryName="JUnit">
    <shortenClasspath name="MANIFEST" />
    <option name="TEST_OBJECT" value="class" />
    <option name="WORKING_DIRECTORY" value="%MODULE_WORKING_DIR%" />
    <method v="2">
        <option name="Make" enabled="true" />
    </method>
</configuration>
<configuration default="true" type="TestNG">
    <shortenClasspath name="MANIFEST" />
    <option name="TEST_OBJECT" value="CLASS" />
    <option name="WORKING_DIRECTORY" value="%MODULE_WORKING_DIR%" />
    <properties />
    <listeners />
    <method v="2">
        <option name="Make" enabled="true" />
    </method>
</configuration>

3) Press "Ctrl + S"

4) After that all new tests will start with Jar MANIFEST
