java - exec-maven-plugin exec :java failing: Cannot assign configuration values to array of type java. lang.String

Question

当执行 mvn exec:java 时，它无法正确解析配置参数，抛出以下错误:

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default-cli) on project autotest-programmes: Unable to parse configuration of mojo org.codehaus.mojo:exec-maven-plugin:1.2.1:java: Cannot assign configuration values to array of type java.lang.String: [-classpath, Classpath {}, --glue, com.company.test.cucumber, --format, pretty, --format, html:C:\workspace\autotest\target] -> [Help 1]

这是使用的插件配置(使用 Apache Maven 3.0.3):

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.2.1</version>

        </execution>
    </executions>
    <configuration>

            <argument>com.company.test.cucumber</argument>
            <argument>--format</argument>
            <argument>pretty</argument>
            <argument>--format</argument>
            <argument>html:${project.basedir}\target</argument>
        </arguments>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-core</artifactId>
            <version>1.0.2</version>
        </dependency>
    </dependencies>
</plugin>

Answer 1

我建议从您的配置中删除空条目并重试。

 <argument>-classpath</argument>
 <classpath/>

因为在 java 目标中，基于 documentation 的类路径是不允许的.

顺便说一句:永远不要在你的 maven pom 中使用“\”。请改用正斜杠。
