运行单元测试时 IntelliJ 错误: 无法找到或加载主类 ${ surefireArgLine }

在 IntelliJ 中运行单元测试时出现以下错: 错误: 无法找到或加载主类 ${ surefireArgLine }。 我使用的是 maven，在 pom.xml 中我有:

<properties>
...
<surefire.argLine />
</properties>


<build>
<plugins>
<plugin>
<groupId>com.mysema.maven</groupId>
<artifactId>apt-maven-plugin</artifactId>

<configuration>
<outputDirectory>target/generated-sources/java</outputDirectory>
<processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
</configuration>
</execution>
</executions>
</plugin>


<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>

<argLine>${surefire.argLine}</argLine>
</configuration>
</plugin>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.1.201405082137</version>
<executions>

</goals>
<configuration>

<destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile>
<!--

-->
<propertyName>surefireArgLine</propertyName>
</configuration>
</execution>
...

是否有人有类似的问题? 如何为 surefireArgLine 设置值？

I found out that I have to run my test case from maven with mvn -Dtest=TestCircle test not directly from IDE.

I was able to fix this error in Netbeans by changing the surefire-plugin version to 2.10 and removing 

<argLine>-Xmx1024m -XX:MaxPermSize=256m ${argLine}</argLine>

from the maven-surefire-plugin configuration. Instead i have created a property argLine that is picked automatically by surefire.

<properties>
<argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
</properties>


<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.10</version>
</plugin>

Now, i can run and debug single files and test methods. And Code Coverage is working as expected.

I had the same problem and i think i found the solution on the vertx-issue tracker.

In short you have to configure your IntelliJ Maven (surefire plugin) integration to behave differently.

This works for me in IntelliJ 14.1.6 with mvn 3.3.9 Preferences -> Build,Execution,Deployment -> Build Tools -> Maven -> Running Tests

For IntelliJ 2019 and above Settings-> Build,Execution,Deployment -> Build Tools -> Maven -> Running Tests

Uncheck argLine

Was looking for this and found this project "fix" it in this thread

Basically define your jacocoArgLine var name as empty project property. Then in surefire configuration use @{jacocoArgLine} instead of dollar prefix.

Update of pom.xml solved my problem.

<argLine>${surefire.argLine}</argLine>

Complete plugin info in pom.xml

    <plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<parallel>classes</parallel>
<threadCount>10</threadCount>
<workingDirectory>${project.build.directory}</workingDirectory>
<jvm>${env.JDK1_8_HOME}\bin\java</jvm>
<argLine>${surefire.argLine}</argLine>
</configuration>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit4</artifactId>
<version>2.18.1</version>
</dependency>
</dependencies>
</plugin> -->

For a more permanent fix for every new project add the following to your IntelliJ IDEA Custom VM Options:

  1. Help > Edit Custom VM options
  2. Add: -Didea.maven.surefire.disable.argLine=true

This will deactivate surefire for all new projects you open.
