问题描述
在我们项目的一个子模块中执行目标 com.adobe.ac:flex-pmd-maven-plugin:1.2:report (run-flexpmd-main) 时，我收到以下错误。>
Failed to execute goal com.adobe.ac:flex-pmd-maven-plugin:1.2:report (run-flexpmd-main) on project sample-Project: An error has occurred in Flex PMD Report report generation. A system exception has been thrown: 0 -> [Help 1]

下面是pom.xml文件中指定的目标配置：
<plugin>
<groupId>com.adobe.ac</groupId>
<artifactId>flex-pmd-maven-plugin</artifactId>
<version>1.2</version>
<configuration>
<failOnError>true</failOnError>
<ruleSet>
${settings.localRepository}/example_dir/flexpmd-rules/${flexPMD_ruleSetVersion}/flexpmd-rules-${flexPMD_ruleSetVersion}.xml
</ruleSet>
</configuration>
<executions>
<execution>
<id>run-flexpmd-main</id>
<phase>process-sources</phase>
<goals>
<goal>report</goal>
</goals>
<configuration>
<sourceDirectory>${project.build.sourceDirectory}</sourceDirectory>
<outputDirectory>${project.build.directory}/pmd/main</outputDirectory>
</configuration>
</execution>
<execution>
<id>run-flexpmd-test</id>
<phase>process-test-sources</phase>
<goals>
<goal>report</goal>
</goals>
<configuration>
<sourceDirectory>${project.build.testSourceDirectory}</sourceDirectory>
<outputDirectory>${project.build.directory}/pmd/test</outputDirectory>
</configuration>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>com.adobe.flexpmd</groupId>
<artifactId>custom-ruleset</artifactId>
<version>0.0.4</version>
</dependency>
<dependency>
<groupId>example_dir</groupId>
<artifactId>flexpmd-rules</artifactId>
<version>${flexPMD_ruleSetVersion}</version>
<type>xml</type>
</dependency>
</dependencies>
</plugin>
我们对所有其他子项目使用相同的规则集，并且报告已成功生成。只有在一个特定的项目中它才会抛出错误。而且我们最近没有对 flexpmd 规则集进行任何更改。当我们将依赖项迁移到新的工件并在迁移后测试构建时，这个问题就开始了。我也尝试将 failonError 设置为 false，但它仍然抛出此错误。任何人都可以帮我们调试这个错误吗？
