java.lang.IllegalStateException:endPosTable已设置

Question

试图建立一个alexa(亚马逊:回声)技能组合.同时,尝试使用这种经验作为通过匕首2依赖注入的学习测试平台.但是,使用maven-2 cmd构建包:

mvn assembly:assembly -DdescriptorId=jar-with-dependencies package'. 

生成具有完整依赖项的zip jar会产生以下异常跟踪:

初始编译很好,所有测试都运行并成功执行.我觉得在"连接"事物向南的依赖关系时.请查看此文件以查看构建期间的控制台输出.

我的问题是,如果尝试使用不同的方式生成依赖项是值得的.我为此目的不太了解maven.是否有可以使用的补丁或其他东西？你认为甚至可以提出一个解决方法吗？我希望能够继续使用dagger 2框架来构建这个项目.

错误报告中描述了该问题JDK-8067747:

(作者Jan Lahoda)

据我所知,这个bug存在两个方面:

1. 它碰到异常的javac错误.我正在研究这个问题,但请注意,当修复此问题时,javac将不会编译输入,它会从Filer抛出一个适当的异常(见下文).

2. 似乎是一个maven bug:当项目使用"clean install"编译时,注释处理器将生成一个源文件到"target/generated-sources/annotations".增量编译完成后,此生成的文件将作为输入传递给javac,注释处理器将尝试再次生成它,这是不允许的.

这意味着当maven bug被修复时,javac用不适当的异常报告问题的bug变得无关紧要.但是,考虑到Maven 2的生命终结的实际日期,我怀疑你可以期待找到它的修复或补丁.

如本期所述，解决方法是禁用useIncrementalCompilation：

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>

    <configuration>
        <useIncrementalCompilation>false</useIncrementalCompilation>
    </configuration>
</plugin>
