【问题描述】：

当我尝试执行 mvn -DskipTests=true -Passembly assembly:directory exec:exec 命令来制作二进制文件时，我得到了 无法在项目 ors 上执行目标 org.codehaus.mojo:exec-maven-plugin:1.6.0:exec（默认）：参数“executable”丢失或无效错误。我还在配置中应用了 Source Target 1.8，但仍然遇到同样的错误。

我通过在 pom.xml 中指定所需的插件解决了这个错误，如下所示

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <executable>java</executable>
                    <arguments>
                        <argument>-classpath</argument>
                        <classpath />
                        <argument>com.ocloud.Alarm.App</argument>
                    </arguments>
                </configuration>
            </plugin>

【解决方案2】：

从 exec-maven-plugin 版本 1.6.0 开始，除非您指定 id，否则 <execution> 块中的 <configuration> 部分将被忽略。

尝试更改您的命令行，将 exec:exec@foo 替换为 exec:exec，并将插件块更改为包含 id foo如下：

      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
          <executions>
              <execution>
                  <id>foo</id>
                  <phase>package</phase>
                  <goals><goal>exec</goal></goals>
                  <configuration>
          <executable>${perl.path}</executable>
                      <arguments>
                          <argument>../tools/scripts/createScript.pl</argument>
                          <argument>${project.build.directory}/${project.artifactId}</argument>
                          <argument>ors</argument>
                          <argument>org.marketcetera.ors.OrderRoutingSystem</argument>
                          <argument>${project.build.directory}/${project.artifactId}</argument>
                          <argument>orsadmin</argument>
                          <argument>org.marketcetera.ors.security.ORSAdminCLI</argument>
                      </arguments>
                  </configuration>
              </execution>
          </executions>
      </plugin>

【解决方案3】：

您忘记在<executable> 标记中指定perl.path 变量。

<executable>${perl.path}</executable>

将此添加到您的 pom 父级：

<properties>
    <perl.path>path/to/perl</perl.path>       
</properties>

【讨论】：

非常感谢你的建议，但我已经在最后一个标签的标签中维护了 ${perl.path}
我明白了。但是你指定 perl.path 变量的值了吗？
我已经在系统变量“C:\Program Files\strawberry\perl\bin”中指定了 perl.path 变量的值。
