我在运行 ant build 时收到 '**** WRONG JAVA VERSION ****'

Question

我的问题不是这个问题，因为我在java版本中没有差异。 在我安装 java 1.8.45（jdk 和 jre）后，运行“ant clean all”的构建失败了。 它说：

**** 错误的 Java 版本 ****

环境检查失败：您使用的 Java 版本不受支持。 请确保您使用的是 Java 1.7 或更高版本。 您当前的 Java 版本是：1.8.0_45

提示：如果您使用的是 eclipse，您可以在 Preferences->Java->Installed JREs 下配置不同的 JVM。

我的系统的详细信息：
爪哇版：

将 echo 添加到构建文件：

与针对同一问题的其他开放线程不同，在这种情况下，所有版本都是一致的，并且 ant 承认它。 尽管如此，它还是给出了这个问题。 任何见解？

Answer 1

知道了！！！
java 1.8.45 与 ant 1.9.1 不兼容。 切换到 java 1.7.67（jdk 和 jre），一切正常。

Answer 2

我们可以配置java版本util.xml位置：${HYBRIS_BIN_DIR}\\platform\\resources\\ant\\util.xml。

考虑我的版本是 1.8，在checkenv下配置 java 版本为contains string="${java.version}" substring="1.8" />

            <if>
            <not>
                <or>
                    <contains string="${java.version}" substring="1.7" />
                    <contains string="${java.version}" substring="1.8" />
                </or>
            </not>
            <then>
