Micronaut exec-maven-plugin 无法将值存储到数组中：ArrayStoreException

Question

我正在使用 maven 插件在 generate-sources 阶段修改一些源文件。我总是得到例外：

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.0.0:java (openapischema-model-description) on project profile-generation: Unable to parse configuration of mojo org.co
dehaus.mojo:exec-maven-plugin:3.0.0:java for parameter arguments: Cannot store value into array: ArrayStoreException -> [Help 1]

问题是由于在 Micronaut 的父 pom 中使用此插件以及 Maven 将插件的配置部分合并在一起的行为。解决方案是将 combine.self="override" 传递给 arguments 部分。

<configuration>
    <mainClass> de.ohmesoftware.javadoctoopenapischema.Enricher</mainClass>
    <includePluginDependencies>true</includePluginDependencies>
    <arguments combine.self="override">
        <argument>-sourcePath</argument>
       <argument>src/main/java/com/gigsky/profile_generation/domain</argument>
    </arguments>
</configuration>

说明：

Micronaut 在其 micronaut-parent-2.0.0.pom 中定义：

<plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>exec-maven-plugin</artifactId>
          <version>1.6.0</version>
          <configuration>
            <executable>java</executable>
            <arguments>
              <argument>-classpath</argument>
              <classpath/>
              <argument>-XX:TieredStopAtLevel=1</argument>
              <argument>-Dcom.sun.management.jmxremote</argument>
              <argument>${exec.mainClass}</argument>
            </arguments>
          </configuration>
        </plugin>

这里 <classpath/> 引起了问题。 Maven 正在将参数部分合并在一起，尽管这些是不同的目标。这可以用 mvn help:effective-pom:

检查

              <goal>java</goal>
            </goals>
            <configuration>
              <mainClass>de.ohmesoftware.javadoctoopenapischema.Enricher</mainClass>
              <includePluginDependencies>true</includePluginDependencies>
