更新 NewRelic 版本在运行时抛出 AbstractMethodError
Updating NewRelic version throwing AbstractMethodError at runtime
我正在将项目中的 newrelic 版本从 2.x.x 更新到 5.x.x。我按照 newrelic 文档中提到的步骤进行操作（我更新了 pom 文件中的依赖版本，更新了代理 jar 文件和配置文件）。
但现在 运行 项目通过了所需的 java 代理：
java -server -javaagent:/Users/amit.upadhyay/abcproject/abcproject-app/newrelic-stage/newrelic.jar -jar abcproject-app/target/abcproject-app-*.*.*-SNAPSHOT.jar /Users/amit.upadhyay/Downloads/abcproject.yml
我得到 java.lang.AbstractMethodError。以下是错误日志：

因为我在运行时遇到 AbstractMethodError，即我在某处使用旧接口，该接口已在新版本的 newrelic java 代理 5.x.x.
中更新
错误日志表明我项目中使用的 xerces 版本与更新的 newrelic java 代理中的版本存在冲突。在谷歌搜索中，我发现这两个 SO 链接 first and second 有类似的问题。根据给出的答案，我添加了
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.11.0</version>
</dependency>
<dependency>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
<version>1.4.01</version>
</dependency>
我的 pom 文件，这个 AbstractMethodError 错误消失了。
但是在 运行 上我又开始遇到这个异常：com.newrelic.agent.config.ConfigurationException
此异常的日志是：
Mar 16, 2020 02:37:18 +0530 [9598 1] com.newrelic INFO: Configuration file not found. The agent will attempt to read required values from environment variables.

现在，我不明白为什么会抛出 ConfigurationException（或者为什么找不到配置文件）。与旧版本的 newrelic 代理（2.x.x 或 3.x.x）一起使用时，相同的 java 命令（代理 jar 和配置文件的路径完全相同）运行完美。
我想了解这里发生了什么wrong/missing？
我能够在我的项目中更新到最新的 newrelic 版本。似乎他们已经更新了 java 代理中的 xerces 版本，其中版本大于 5.0.0。随着更新 xerces 版本的修复，我需要将 newrelic 配置文件作为系统属性显式传递以解析 ConfigurationException.
总体总结：
- 将这些库更新为
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.11.0</version>
</dependency>
<dependency>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
<version>1.4.01</version>
</dependency>
并将 newrelic 配置文件作为系统传递 属性:
-Dnewrelic.config.file=./${NEW_RELIC_DIR_NAME}/newrelic.yml
我正在将项目中的 newrelic 版本从 2.x.x 更新到 5.x.x。我按照 newrelic 文档中提到的步骤进行操作（我更新了 pom 文件中的依赖版本，更新了代理 jar 文件和配置文件）。
但现在 运行 项目通过了所需的 java 代理：
java -server -javaagent:/Users/amit.upadhyay/abcproject/abcproject-app/newrelic-stage/newrelic.jar -jar abcproject-app/target/abcproject-app-*.*.*-SNAPSHOT.jar /Users/amit.upadhyay/Downloads/abcproject.yml

因为我在运行时遇到 AbstractMethodError，即我在某处使用旧接口，该接口已在新版本的 newrelic java 代理 5.x.x.
错误日志表明我项目中使用的 xerces 版本与更新的 newrelic java 代理中的版本存在冲突。在谷歌搜索中，我发现这两个 SO 链接 first and second 有类似的问题。根据给出的答案，我添加了
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.11.0</version>
</dependency>
<dependency>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
<version>1.4.01</version>
</dependency>
我的 pom 文件，这个 AbstractMethodError 错误消失了。
但是在 运行 上我又开始遇到这个异常：com.newrelic.agent.config.ConfigurationException
此异常的日志是：
Mar 16, 2020 02:37:18 +0530 [9598 1] com.newrelic INFO: Configuration file not found. The agent will attempt to read required values from environment variables.

现在，我不明白为什么会抛出 ConfigurationException（或者为什么找不到配置文件）。与旧版本的 newrelic 代理（2.x.x 或 3.x.x）一起使用时，相同的 java 命令（代理 jar 和配置文件的路径完全相同）运行完美。
我想了解这里发生了什么wrong/missing？
我能够在我的项目中更新到最新的 newrelic 版本。似乎他们已经更新了 java 代理中的 xerces 版本，其中版本大于 5.0.0。随着更新 xerces 版本的修复，我需要将 newrelic 配置文件作为系统属性显式传递以解析 ConfigurationException.
总体总结： - 将这些库更新为
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.11.0</version>
</dependency>
<dependency>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
<version>1.4.01</version>
</dependency>
并将 newrelic 配置文件作为系统传递 属性:
-Dnewrelic.config.file=./${NEW_RELIC_DIR_NAME}/newrelic.yml
