java.lang.NoSuchFieldError: DEF_CONTENT_CHARSET from linux terminal with twilio
java.lang.NoSuchFieldError: DEF_CONTENT_CHARSET from linux terminal with twilio
在 CentOS 终端的 java 小程序 运行 中，当我在 CentOS 7 终端输入 java -cp .:"../dependencies/*" mainpackage.SendText xxxxxxxxxx HelloThere 时出现 java.lang.NoSuchFieldError: DEF_CONTENT_CHARSET 错误。 如何解决此错误，以便程序可以从命令行 运行 成功？
终端输入输出如下：
[user@domain bin]$ java -cp .:"../dependencies/*" mainpackage.SendText xxxxxxxxxx HelloThere
Exception in thread "main" java.lang.NoSuchFieldError: DEF_CONTENT_CHARSET
at org.apache.http.impl.client.DefaultHttpClient.setDefaultHttpParams(DefaultHttpClient.java:175)

at com.twilio.sdk.TwilioRestClient.<init>(TwilioRestClient.java:110)
at mainpackage.SendText.main(SendText.java:20)
其中 xxxxxxxxxx 和 HelloThere 是程序的参数，如下所示。
注意代码的目录结构为：
/home/user/javacode #contains SendText.java
/home/user/javacode/bin/mainpackage/ #contains SendText.class
/home/user/javacode/dependencies #contains jar files
我读到 this other posting 指出问题是由 classpath 中的 httpcore 的冗余版本引起的，所以我移动到父目录并对所有文件进行了递归搜索他们的名字中带有 httpcore，但得到了以下结果，似乎只显示了 httpcore 的一个版本：
[user@domain bin]$ cd /home/user/javacode/
[user@domain javacode]$ find . -name "*http*"

[user@domain 4.2.3]$
那么如何解决这个错误并从命令行将这个程序成功运行？
答案：
解决方案是将终端导航到 dependencies 目录，然后键入以下四个命令，然后再次尝试从命令行 运行 java 代码：
rm httpclient-4.2.3.pom
rm httpclient-4.2.3.pom.sha1
rm httpclient-4.2.3.jar
rm httpclient-4.2.3.jar.sha1
一位用户在下面的这个大方向上暗示了一个猜测，所以我将其标记为已接受的答案。但实际的解决方案是四行 rm 命令，它消除了冗余的 httpclient 库。
如果您在 运行 时得到一个 NoSuchFieldError，最可能的解释是至少一个 class 的不同版本在 运行 时出现是在编译时出现的，和一个class你正在尝试使用引用一个编译时版本的字段class，它不存在于相同 class 的 运行 时间版本。
很难判断不兼容的确切位置，但我的第一个猜测是httpclient 和httpcore 的不兼容版本。请注意，虽然您只有后者的一个版本，但您有前者的两个版本。我想最有可能的是版本号完全匹配的 httpclient 和 httpcore 是打算一起工作的。
在 CentOS 终端的 java 小程序 运行 中，当我在 CentOS 7 终端输入 java -cp .:"../dependencies/*" mainpackage.SendText xxxxxxxxxx HelloThere 时出现 java.lang.NoSuchFieldError: DEF_CONTENT_CHARSET 错误。 如何解决此错误，以便程序可以从命令行 运行 成功？
终端输入输出如下：
[user@domain bin]$ java -cp .:"../dependencies/*" mainpackage.SendText xxxxxxxxxx HelloThere

然后查看依赖的上面ls -al里面的文件夹内容有没有内容，结果如下，好像是空的：
[user@domain dependencies]$ cd /home/user/javacode/dependencies/1.2/
[user@domain 1.2]$ ls -al

drwxrwxr-x 2 user user 6 Aug 22 05:05 .

[user@domain 4.2.3]$
那么如何解决这个错误并从命令行将这个程序成功运行？
答案：
解决方案是将终端导航到 dependencies 目录，然后键入以下四个命令，然后再次尝试从命令行 运行 java 代码：
rm httpclient-4.2.3.pom
rm httpclient-4.2.3.pom.sha1
rm httpclient-4.2.3.jar
rm httpclient-4.2.3.jar.sha1
一位用户在下面的这个大方向上暗示了一个猜测，所以我将其标记为已接受的答案。但实际的解决方案是四行 rm 命令，它消除了冗余的 httpclient 库。
如果您在 运行 时得到一个 NoSuchFieldError，最可能的解释是至少一个 class 的不同版本在 运行 时出现是在编译时出现的，和一个class你正在尝试使用引用一个编译时版本的字段class，它不存在于相同 class 的 运行 时间版本。
很难判断不兼容的确切位置，但我的第一个猜测是httpclient 和httpcore 的不兼容版本。请注意，虽然您只有后者的一个版本，但您有前者的两个版本。我想最有可能的是版本号完全匹配的 httpclient 和 httpcore 是打算一起工作的。
