gradle - 为什么 gradle 会忽略我的最大堆大小并使用默认值 512MB？

问题描述

我已经设置了环境变量JAVA_TOOL_OPTIONS=-Xms1024m -Xmx8192m，我从 Gradle 构建中收到了这个错误：

2021-04-06T11:49:15.294+0100 [QUIET] [system.out] Error occurred during initialization of VM
2021-04-06T11:49:15.295+0100 [QUIET] [system.out] Initial heap size set to a larger value than the maximum heap size

为了解决这个问题，我尝试将以下内容添加到顶级build.gradle文件中：

allprojects {
    // ...

    test {
        minHeapSize = "1g"
        maxHeapSize = "8g"
    }
}

过去，为测试设置最大堆大小已经解决了这个问题。但在这种情况下，它没有。Gradle 仍在将最大堆大小设置为 512MB，如下所示。（我用****下面的替换了一些子字符串。）

为什么 Gradle 6.5.1 忽略我的maxHeapSize？

另一个 Gradle 文件中有另一个test块，但没有其他maxHeapSize.

标签： gradle

解决方案

这是由于在同一个 Gradle 模块中启用了 jacoco 和 scoverage 插件造成的。这些是 Scala 模块，所以我只是从这些模块中删除了 jacoco 插件，然后它就可以工作了。
