是否可以使用Java 8和Install4j 5.1.5生成无警告的安装文件 [英] Is it possible to generate with Java 8 and Install4j 5.1.5 a warning free installation file

问题描述

我们正在使用Install4j 5.1.5，install4j-maven-plugin 1.0.5和Java 8 EA Build124.

We are using Install4j 5.1.5, install4j-maven-plugin 1.0.5 and Java 8 EA Build 124.

在生成安装文件期间，我们从install4j(超过100页)中收到了一些警告

During installation file generation we got couple of warnings from install4j (more than 100 pages)

 [warning] major version should be between 45 and 51 for JDK <= 1.7 

因此，我们有了一个安装文件，但是是否可以得到一个没有警告的安装文件?是否存在隐藏的开关以禁用JDK版本检查?

As a result we have a installation file, but is it possible to got a warning free installation file? Exist a hidden switch to disable JDK version check?

配置:

应用程序是第二个maven模块的一部分，并使用JDK 8进行编译.我们正在使用Java 8的语言功能.

Application is part of a second maven module and compile with JDK 8. We are using language feature of Java 8.

Install4j maven模块使用实际的Java8运行时以及以下编译器设置

Install4j maven module use actual java8 runtime and following compiler settings

 <maven.compiler.source>1.7</maven.compiler.source>
 <maven.compiler.target>1.7</maven.compiler.target>

如果将编译器目标更改为1.8，则会在install4j内的自定义视图组件中出现编译器错误

If we change compiler target to 1.8 we got a compiler error in a custom view component inside from install4j

 java.lang.UnsupportedClassVersionError: ... Unsupported major.minor version 52.0
 ....

 [INFO]  at com.install4j.b.c.a.a(ejt:849)
 [INFO]  at com.install4j.b.c.a.a(ejt:820)     

在我看来，我们在xerces代码生成中遇到了问题

It seems to me we got here a problem inside xerces code generation

推荐答案

这是因为install4j不支持Java 8，但是它仍然可以正常工作.

It is because install4j doesn't support java 8 but it does works anyway.
