问题描述
我有一个使用PhantomJS的项目.有一个可以自动安装的插件:
I have a project using PhantomJS. There is this plugin that will install it automatically:
<plugin>
<groupId>com.github.klieber</groupId>
<artifactId>phantomjs-maven-plugin</artifactId>
<version>0.2.1</version>
<executions>
<execution>
<goals>
<goal>install</goal>
</goals>
</execution>
</executions>
<configuration>
<version>1.9.2</version>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<systemPropertyVariables>
<phantomjs.binary>${phantomjs.binary}</phantomjs.binary>
</systemPropertyVariables>
</configuration>
</plugin>
我收到此错误:

添加这些内容(根据此线程):
Adding these (according to this thread):
<dependency>
<!-- For the PhantomJS install plugin -->
<groupId>de.schlichtherle.truezip</groupId>
<artifactId>truezip-driver-file</artifactId>
<version>7.7.9</version>
</dependency>
<dependency>
<!-- For the PhantomJS install plugin -->
<groupId>de.schlichtherle.truezip</groupId>
<artifactId>truezip-kernel</artifactId>
<version>7.7.9</version>
</dependency>
<dependency>
<!-- For the PhantomJS install plugin -->
<groupId>de.schlichtherle.truezip</groupId>
<artifactId>truezip-driver-zip</artifactId>
<version>7.7.9</version>
</dependency>
没有帮助(我收到相同的错误消息).
does not help (I get the same error message).
但是:二进制文件确实已下载并解压缩.系统属性被设置.依赖于此工作的测试可以完美运行.
However:The binary does gets downloaded and unzipped. The system property gets set. The tests that depend on this working run perfectly.
还
$ mvn dependency:tree | grep truezip
[INFO] +- de.schlichtherle.truezip:truezip-driver-file:jar:7.7.9:compile
[INFO] +- de.schlichtherle.truezip:truezip-kernel:jar:7.7.9:compile
[INFO] +- de.schlichtherle.truezip:truezip-driver-zip:jar:7.7.9:compile
[INFO] | +- de.schlichtherle.truezip:truezip-swing:jar:7.7.9:compile
...因此仅包含一个版本.
... so only one version is included.
推荐答案
我对PhantomJS不太了解,但是正如您所知,异常是由关闭挂钩抛出的.该挂钩是一个安全网,可通过TrueZIP提交对归档文件的所有未决更改.您可以在JVM终止之前调用de.schlichtherle.truezip.file.TVFS.umount()
轻松地将其删除.请将该调用包装在finally
块中,以确保即使应用程序以Throwable终止,该调用也会被调用.
I don't know much about PhantomJS, but as you figured the exception is thrown by a shutdown hook. This hook is a safety net which commits any pending changes to archive files by TrueZIP. You can easily remove it by calling de.schlichtherle.truezip.file.TVFS.umount()
just before the JVM terminates. Please wrap the call in a finally
-block to ensure it gets called even if the application terminates with a Throwable.
这篇关于TrueZip:NoClassDefFoundError(但仅适用于关机钩子?)的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
