How to specify javax.xml.accessExternalSchema for the JAXB2 Maven plugin
提问by Josh
I have a maven plugin (jaxb2) and I need to supply a jvm arg to it. I don't think there is a tag to add jvm args in the pom for it.
我有一个 Maven 插件（jaxb2），我需要为它提供一个 jvm arg。我不认为有一个标签可以在 pom 中为它添加 jvm args。
I know I can pass in jvm args on the command line eg: mvn clean install -Djavax.xml.accessExternalSchema=all
我知道我可以在命令行上传递 jvm args 例如： mvn clean install -Djavax.xml.accessExternalSchema=all
Is it possible to set this jvm arg in the pom so that I don't have to type it into the command line every time?
是否可以在 pom 中设置这个 jvm arg，这样我就不必每次都在命令行中输入它？
(As aside - this jvm arg is required in order for it to work with JAVA-8. It works fine with JAVA-7)
（顺便说一句 - 这个 jvm arg 是必需的，以便它与 JAVA-8 一起工作。它与 JAVA-7 一起工作正常）

This is relevant to the new XML security properties in JAXB 1.5, introduced in Java 8. This is why your builds now fail on Java 8 but work with Java 7.
这与Java 8 中引入的JAXB 1.5 中的新XML 安全属性相关。这就是您的构建现在在 Java 8 上失败但可以在 Java 7 上工作的原因。
If you're using my maven-jaxb2-plugin, please upgrade to the version 0.9.0or later (current is 0.10.0). It has now a accessExternalSchemaswitch (default is all).
如果您使用的是 my maven-jaxb2-plugin，请升级到 版本0.9.0或更高版本（当前为0.10.0）。它现在有一个accessExternalSchema开关（默认为all）。
This sets precisely javax.xml.accessExternalSchema=all.
这正好设置javax.xml.accessExternalSchema=all。
Please see the documentation.
请参阅文档。

Take a look at the Maven Compiler Plugin. Specifically you should be able to use the <compilerArgument>element to pass settings to the compiler.
查看 Maven 编译器插件。具体来说，您应该能够使用该<compilerArgument>元素将设置传递给编译器。
See http://maven.apache.org/plugins/maven-compiler-plugin/examples/pass-compiler-arguments.htmlfor examples.
有关示例，请参阅http://maven.apache.org/plugins/maven-compiler-plugin/examples/pass-compiler-arguments.html。

If you are trying to change the behavior of the JVM that is running Maven itself, add options to MAVEN_OPTS in the environment before launching mvn.
如果您尝试更改运行 Maven 本身的 JVM 的行为，请在启动 mvn 之前向环境中的 MAVEN_OPTS 添加选项。

I came across this issue while working with jaxb2-maven-plugin. I found a related jira issue for maven-jabx2-plugin - https://java.net/projects/maven-jaxb2-plugin/lists/issues/archive/2014-03/message/0

According to this issue Stephan202 suggested using properties-maven-plugin which worked like charm. Here is a sample code from his post -
根据这个问题，Stephan202 建议使用 properties-maven-plugin ，它的作用就像魅力一样。这是他的帖子中的示例代码 -

Re; the post - "I needed a solution that doesn't use alpha versions as that is my companies rules. –"
关于; 帖子 - “我需要一个不使用 alpha 版本的解决方案，因为这是我公司的规则。-”
Changing the version to 1.0 & the value to 'all' got it working for me:
将版本更改为 1.0 并将值更改为“全部”使其对我有用：
