java - 在执行 org.codehaus.mojo :exec-maven-plugin:1. 6.0 :exec: java. lang.String 时无法转换为 org.codehaus.mojo.exec.Modulepath

Question

仅当将“-p”添加到 org.codehaus.mojo:exec-maven-plugin:1.6.0:exec 插件时，以下 pom.xml 执行才会失败，删除此参数后它运行正常，但我需要争论，有什么建议吗？

这是 pom.xml:

<plugin>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.6.0</version>
  <groupId>org.codehaus.mojo</groupId>
  <executions>
    <execution><!-- script -->
      <id>creating-war</id>
      <phase>generate-sources</phase>
      <goals>
        <goal>exec</goal>
      </goals>
      <configuration>
        <properties>
          <workspace.location>/space/workspaces/workspace/branch/</workspace.location>
          <property.file>/space/properties</property.file>
      <output.dir>${project.build.directory}/ser
        <properties>
          <workspace.location>/space/workspaces/workspace/branch/</workspace.location>
          <property.file>/space/properties</property.file>
          <output.dir>${project.build.directory}/servoy</output.dir>
          <script.location>/opt/developer/exporter</script.location>
          <admin.username>admin</admin.username>
          <admin.password>admin</admin.password>
          <main.app>app_main</main.app>
        </properties>voy</output.dir>
        <script.location>/opt/developer/exporter</script.location>
        <admin.username>admin</admin.username>
        <admin.password>admin</admin.password>
        <main.app>app_main</main.app>
          </properties>
          <executable>./war_export.sh</executable>
          <workingDirectory>${script.location}</workingDirectory>
          <arguments>
            <argument>-s</argument>
            <argument>${main.app}</argument>
            <argument>-o</argument>
            <argument>${output.dir}</argument>
            <argument>-data</argument>
            <argument>${workspace.location}</argument>
            <argument>-p</argument>
            <argument>${property.file}</argument>
            <argument>-defaultAdminUser</argument>
            <argument>${admin.username}</argument>
            <argument>-defaultAdminPassword</argument>
            <argument>${admin.password}</argument>
          </arguments>
        </configuration>
      </execution>
    </executions>
  </plugin>

这是运行 mvn clean install 后来自控制台的错误跟踪:

Answer 1

这是一个 exec-maven-plugin错误，已报告 here并且还没有解决。建议的短期解决方法是添加 <longModulepath>false</longModulepath>可选参数。
